    The invention relates to a person lying to the measurement of the human body in a lying position for performing radiological imaging medical examinations by X-ray, tomography, nuclear magnetic resonance and other imaging methods for the holistic detection of body statics in a lying position, namely for detecting the position of the skeleton in relation to its central axis and any distortions of the shoulder and / or hip.
    With imaging methods representations of structure and function of the tissues and organs in the body are determined in medical diagnostics. For this purpose, in particular methods of nuclear magnetic resonance (such as MRI - Magnetic Resonance Imaging) or ultrasound are used. X-ray diagnostics is also a widespread imaging method for detecting anomalies in the body, in that differently dense body tissue absorbs the X-rays differently, which can be reproduced accordingly. In computed tomography (CT), the X-ray images are electronically exploited, whereby such images record a significantly higher image quality. Other methods rely on radionuclide techniques, infrared radiation, impedance or visible light to acquire body image data.
    Statements that can not be made in any of the above-mentioned apparatus examination methods, information on body statics. Without this information, there is always uncertainty as to how far the images reflect only a momentary body situation. The variations of the body situation, however, are sensitive to the overall picture. Stress situations or pain in the patient lead to different muscle tensions and thus to avoidance postures that would best be measured on the skeleton itself. Such tension can be built up over a long time, but also occur acutely, which is why every stress situation and every pain perception shows an individual tension pattern. Relevant for the assessment is the knowledge of the causes of the deviations in the imaged position from the normal position, otherwise this can lead to erroneous conclusions.
    Lack of information about the body statics in the image recordings, the deviations from the target state, first, are not identifiable, and secondly not assignable. And third, after a therapy, a new image acquisition can not be interpreted correctly, because both qualitative and quantitative comparisons with the earlier image are not or only very insufficiently possible. The patient may be lying on the couch after a therapy with a substantially different body statics and therefore the new picture then also shows a changed situation that is not or not sufficiently comparable due to an image taken with other body statics. The more expensive images are therefore interpreted with very inadequate quality and do not allow a quantitative recording of changes in the body statics at all.
    The resulting by the tension different leverage inside the body change the skeletal bones, joints and whirl positions and also affect the organs. A skeleton is not stable in itself, which is why the muscle failure stresses move and distort the skeleton with its bones, joints and vertebrae. As an example, only the resultant of the tension can be seen on an MRI or CT scan. In the case of medical clarifications, the collection of body measurement data is omitted, which is why static deviations are detected at most indirectly and only insufficiently on the basis of the resulting image. To investigate the cause of the tension, but the tension would first have to be measured exactly and their extent determined. The latter would be highly advisable, especially in the case of complicated, irreversible interventions, so that the cause of the tension or of what is detected as defective on the MRI, CT, ultrasound or similar images is addressed. Due to the lack of holistic information on the clinical picture, symptomatic images are often used as a basis for surgical interventions, which could possibly have been prevented by targeted control of the causes. Or else even wrong therapies are prescribed, which instead of the causes only fight the symptoms and thus the causes of a complication in the patient remain untreated and unresolved.
    A common example is the diagnosis of a worn hip joint or the so-called hip joint arthrosis. The patient suffers from severe pain due to wear on the acetabulum surface of the acetabulum and femoral femoral head. Too often, such a hip joint is partially or completely replaced by an artificial joint, without the cause of osteoarthritis to get to the bottom. However, the reason for the wear is often an obliquity of the pelvis, resulting in a decades-long one-sided wear of the hip joint. The cartilage between hip socket and femoral head is overloaded and heavily worn, which ultimately causes the arthritis. Such causes of unilateral wear are unfortunately ignored. This can be compared with the one-sided wear of a car tire, if only the tire is replaced, but the cause, the misaligned steering geometry, is not discovered and corrected by surveying. However, implanting an unnecessary endoprosthesis, that is, a replacement part that is foreign to the body, always means exposing the patient to unnecessary risks, not to mention the cost of health care. Inserting an artificial hip joint poses the risks of mitteischweren, surgical intervention. The most common complications of such surgery include thrombosis, infection, post-operative bruising (haematomas), rebleeding or even nerve and blood vessel injuries. Also, blood loss can occur during the surgery, whereby the patient must be supplied with own blood or foreign blood. There is also the possibility of an implant allergy in which the body of the patient is allergic to components of the endoprosthesis, which, as in infection, a revision surgery is necessary. Thus, placement of an endoprosthesis should be considered as a last resort if targeted, cause-fighting, therapeutic treatments for hip osteoarthritis have failed.
    The research for the cause is usually complex because the causes of pain and problems in a particular body area are not rare elsewhere, or triggered in a completely different body region. Without the digestion by means of physical data, it is almost unsuccessful to search for the cause decoupled from the point of pain or inflammation. On the other hand, these causes are obvious on the basis of often slight deflections, dislocations, obliquity, etc. of the skeleton. Therefore, one can not avoid judging the data of the imaging techniques for a careful diagnosis with the inclusion of these body static survey data.
    A device is known for measuring the human body in an upright, standing position from EP 1 408 833 B1. In this case, the man to be surveyed stands in his natural position on two decoupled scales, with his left foot on a scale and the right on the other. These two scales form the lowest part of the approximately man-high measuring device. Above it is the framework on which the movable measuring rods for body measurement are arranged. Based on the error from the difference of the balance displays for a given, but of course, ingestible foot position lateral hip deviations, lateral upper body deviations, twists, knee positioning angle, knee extensor deficits, hollow back, shoulder high etc. are mechanically measured. Here, calibrated measuring rods are moved manually to the corresponding body points until standstill due to the body resistance. At the stop, the displayed measuring value is noted. The dipsticks can be moved both horizontally and vertically to accommodate the different body masses. This allows deviations in the statics for the whole body to be reproducibly and accurately recorded.
    A problem with such a device is that the measurement of the body can only be performed on a person standing. For this purpose, the measuring method is time-consuming, since the respective measuring rod has to be introduced manually at each point and the measuring value is noted down individually. This usually takes about 10 to 20 minutes. Now, when clarification examinations are carried out on a patient in the hospital, this means a great deal of work for the examining physicians as well as for the assistant personnel, so that even for only half an hour examinations one must often take hours of waiting time. For a measurement of the body by means of a device from EP 1 408 833 B1 as described, even additional time would have to be planned, which in view of the tight examination plan should hardly be practicable.
    The measurement on a device as described will not rarely give a distorted image of the person to be measured, because the latter will hardly stand naturally in this particular situation. If the person focuses on their natural posture, they will unconsciously stretch or tense at various points. In addition, it is impossible for the person to be surveyed to hold the same posture for a quarter of an hour. It inevitably leads to subtle posture changes. An image thus obtained is always faulty.
    Often patients who have to undergo imaging procedures such as MRI, CT, ultrasound, etc., are ill and suffer from pain, which is why they are limited in their freedom of movement. In such a case, it would be unreasonable for a person to have to undergo a 15-minute or longer measurement of their body standing up. By contrast, in the aforementioned imaging methods and in some cases also in X-ray images, the patients can remain lying down during the entire image recording process. This also contributes to their relaxation.
    The most accurate relationship between the body measurement data and the image information of an imaging method results from its simultaneous determination. Then, for example, an MRI image of a particular body part most closely matches the survey data if the image acquisition and the survey were made in the same body position of the subject. Thus, the causal link between complaint and cause can be seen from the picture drawn up by the two sources.
    The object of the invention is mindful of the above-described embodiments is to provide a patient bed with detection device for body statics, with the three-dimensional position of the body skeleton based on the position of the feet as they are positioned when standing, with the position and Alignment of the joints, the pelvis, the spine, the shoulders and the head can be measured while lying, and the bearing load of the body is detected at each point, so that asymmetries, inconsistencies and distortions can be quantified measured and allow conclusions about local tension.
    As a special feature, the patient bed with this detection device is to supplement the existing imaging methods with a new data dimension, in that the details of these image recordings with the surveying data of said detection device provide a comprehensive overall picture of the body and its body statics in relation to the complaint. This detection device should be designed simply and optionally be used on a recumbent patient during an imaging procedure.
    The object of the invention achieved by a passenger lounger for performing radiological imaging medical examinations by means of X-ray, tomography, magnetic resonance and other imaging techniques, in which a person in a horizontal position, shots and other images are created, characterized in that the Couch with a detection device is equipped for optical, laser-optical mechanical or electromechanical measurement of the patient's body or specific locations of the patient's body, with footrests for positioning the soles of the feet as standing on vertical support surfaces with natural foot spread, as well as for detecting at least the Positions of the knee joints, the hip joint, the pelvic bone, the shoulders and the head, and that the couch is equipped with pressure sensors, for measuring the local support weights of the various resting body parts, for reproducible Erfas the position of the skeleton with respect to its central axis and any distortions of the shoulder and / or hip.
    By gaining this information and data, a targeted therapy is possible thereafter, and by re-measuring and creating a corresponding image can then quantify the change and correctly classify and demonstrate a successful therapy.
    The invention is illustrated in the figures with reference to exemplary embodiments and described and explained below.
    It shows:

    Fig. 1 shows the survey using the example of a standing man who has a pelvic obliquity. On his left foot he carries 15 kg less than on the right, which occurs more often than one would like to think. The pelvic obliquity causes his right leg to be shortened by 25 mm compared to his left leg. Such tension-related skeletal changes are usually accepted as given differences in length, rather than being checked for their causes. In most cases, the difference in length is due to false voltages and can be cured with a manual therapy for long-term length compensation.
    Although it is the muscles, tendons and ligaments that hold a body together rather than the skeleton, the muscle lines are given very modest attention. Bones and joints, on the other hand, are only transmission levers for the muscles. Especially the muscle-tendon approaches are prone to pain, because the transmission of body-internal leverage takes place among other things on them. They are mainly located near the joint, which is why the joints are blamed for the pain. But this only identifies the point overload. Information about the actual Schmerzerreger give the muscle lines, which were distorted by the evasive attitude. Only when they are released from their tense position, the skeleton can be returned to its optimal, symmetrical as possible position.
    Fig. 2 shows a passenger chair 1 for performing radiological medical imaging examinations by means of X-ray, tomography, nuclear magnetic resonance and other imaging methods, which is suitable with a detection device for measuring the position of the individual body parts and the local weight load and even can provide a three-dimensional image of the recumbent patient. With the imaging process, which is recorded in the tube 2, can be created by a person in a lying position, shots and other images. For this purpose, the person is pushed in a lying position on the couch 1 in the tube 2, wherein then the imaging techniques are applied. But previously, the exact position of the patient on the couch 1 will now be measured with the detection device, so that later, for example, after a therapy, comparable with newly measured body positions as a reference. In the example shown, the detection device includes two laser 3D scanners 3, each resting on articulated arms 4, which are pivotable in each direction, and the scanners 4 are pivotally mounted on the ends of these arms in all directions. Below the arms 4 are guided along rails 5 of the length of the couch 1 to slidably. In this way, the laser 3D scanners 3 can in any case take up an optimum position for scanning a person lying on the couch. Suitable 3D scanners for such applications as the Go! SCAN 50 scanner from Inspeck Inc. Montreal, Quebec H2X 2V1, Canada function as described in EP 1 811 726, that is, they form a self-referencing system and a three-dimensional scanning device. Such optical 3D sensor technologies enable the acquisition of a large amount of data on object surfaces at very high speeds, so that a very high density of points can be achieved in real time. With a framework for generating high-precision points based on this huge amount of data, it is ultimately possible to photogrammetrically represent a body so that mass can be detected on it. An intelligent measurement process, the data framework, real-time processing, calibration and the acquisition model are essential elements of the technical fundamentals that ultimately make such high-precision optical 3D measurement systems possible. The recording is made when a patient first rests with his feet in the footpegs 6, as shown in FIG. These footpegs serve to position the feet in a recumbent position as if the patient were standing. In this position, the feet are held with the detents 6, namely the bearing surfaces for the feet in the two footpegs 6 are in the same plane, because they imitate the floor. However, one foot may be skewed in the footrest 6 according to the individual foot position of the patient. The aim is to scan the body in a lying position as far as possible in such a body statics, which it also takes while standing. In particular oblique positions, distortions of the hip, the hip joints, the spine and thus the shoulders and the head are to be detected in this way.
    In addition, the chaise 1 is equipped with a variety of pressure sensors, so that the support load can be detected at any point. A suitable flat pressure sensor for this purpose is, for example, the Interlink FSR406 square pressure sensor from Interlink Electronics, Inc., 546 Flynn Road, Camarillo, CA 93 012, USA. This pressure sensor FSR406 can measure in the range from approx. 10 gram to 10 kg of weight and is 43.7 x 43.7 mm large and only 0.46 mm high. The active area measures 39.6 x 39.6 mm. These square sensors are arranged in a checkerboard pattern over the entire couch 1. These pressure sensors act in a similar way to membrane switches, but in contrast to conventional switches, they change the resistance when pressure is applied in the normal direction. A finger pressure of 10 g to 10 kg on a sensor causes the resistance to drop from approx. Approx.> 1 MΩ to approx. <3 kΩ. The pressure sensors Interlink FSR400 and FSR 400short are also suitable, they only have a round sensitive area of 5.08 mm or 5.6 mm diameter, with a total diameter of 7.62 mm and a height of 0.3 mm. Their sensor surface is self-adhesive, so that they are installed directly in the layer structure of the couch 1, on which they are only covered by a protective layer on which the patient then effectively lies.
    Fig. 3 shows a passenger chair 1 seen in an oblique plan view from the foot side, with a schematically drawn lying on the person with the measuring points indicated by arrows for detecting the position of the various body parts. On the foot side you can see the two footpegs 6 and double arrows indicate how they can be moved. The shift to the left and right is synchronized so that they always have the same distance from the longitudinal center axis of the bed 1. If, for example, a person has legs of different lengths or supposedly different lengths of legs, then, after lying on the couch 1, the footrest 6 is moved up to the foot of the shorter leg until the foot rests satisfactorily on the support surface in the footrest 6, such as if the person would stand on it, with their natural foot position. Afterwards, the other footpeg 6 is pushed against the other foot until the two bearing surfaces are at the same height and the foot also rests satisfactorily on the same. This simulates standing on the floor. The footpegs have between them a distance A of about 5cm. In this defined foot position, the person will take a very personal position, with quite typical position of the knee and hip joints, the pelvic bone, the spine and shoulder and the head. As shown in the example shown, as in most cases the body is not exactly symmetrical. Here the pelvic bone is twisted slightly clockwise, the spine makes an S and the shoulder is crooked, with the right shoulder lower than the left. The knees are not at the same distance from the longitudinal center axis of the bed. It is now important to grasp exactly this typical situation of this person very precisely. For this purpose, in the simplest case, the body parts are measured on the arrows, that is, the distance from the edge of the couch from. A scale 7 on the couch 1 itself can be helpful. The measurement can be carried out mechanically, electromechanically or optically by means of laser distance measuring devices, as will be shown and described below. In addition, it can be seen in Fig. 3 on the basis of the different sized dotted circles below the various contact points of the body that this rests there with different weights on the surface of the chaise 1. These weights can be measured with pressure sensors, as already mentioned for Fig. 2.
    Fig. 4 shows a passenger chair 1 with a person lying on it seen from the side, with the bodies on the body whose height is measured from the level of the surface of the passenger lounger. About the couch 1 here a frame 8 is installed, on which above two laser distance measuring devices 9 along a respective rail 10,11 is slidably mounted, and the rails 10,11 are in turn and transversely to the frame 9 slidably mounted on the frame 8. The frame 8 can be designed to be lowered on the couch 1, so that it can be removed after making the measurement, or it is designed to be rollable or slidable over the lounger 1. With the distance devices 9 on the frame, the distance to the parts to be measured body parts can be measured with sufficient accuracy, contactless and quickly, and the data can be read into a computer. As a laser distance measuring device 9 is for example the Leica Disto D210 laser rangefinder from Leica Geosystem AG in CH-Heerbrugg, Switzerland. This small and handy device measures with an accuracy of ± 1.0 mm and is equipped with a self-timer for precise measurements without moving the device. The data can be read and recorded or read directly to a computer and can be further processed there. In particular, the distance to the following parts of the body are measured: To the two kneecaps, to the two hip joints, to the uppermost points of the pelvic bone, to the shoulders, to the forehead - as indicated by arrows. From the distances, the distances from the surface of the couch 1 can be calculated up to these uppermost points, and together with the horizontally measured distances results in an exact picture of the body position, on any skews and twists. The various bearing weights on the heels, thighs, buttocks and the back and shoulders and the head reveal the uniformity support weights at these body parts and any imbalances are detected by means of pressure sensors in the couch 1, as explained in more detail with reference to FIG becomes. Together with the distance data, the body statics can be determined properly, which allows conclusions about the causes, which can then be treated.
    Fig. 5 shows a passenger lounger, which is equipped with a plurality of square pressure sensors 13, and with a skeleton and the entities to be measured on it, which are measured with lateral laser distance measuring devices 14, each along a rail 15 are displaceable, which extends on both sides of the couch in the longitudinal direction. So it is the location of the head, the shoulder joints, the hip bone, the hip joint and the knee joints. The feet are placed in a symmetrical position to the central axis in the footpegs 6, but not as shown here on the skeleton, but in such a way that the soles lie flat against the stop surfaces, as if the person would stand on their feet. The feet can stand in different spread angles to each other, just as the person concerned is effectively and individually at rest. This footrest proves to be enormously important, because it determines the body position above the feet, even in a lying position. The hip joints, for example, are correspondingly twisted, the pelvis also, and obliquity at the hip and shoulder as well as lateral deviations from the central axis are visible and measurable. Here, these lateral distances are carried out by means of the two laser distance devices 14. For the weight of the various body parts, the pressure sensors 13 are used, as already mentioned in Fig. 2 and explicitly shown here as square sensors in a checkerboard pattern over the entire couch 1 are arranged.
    Fig. 6 shows a single corner of the passenger chair 1 with a simplest mechanical detection device for the body position, without electronic or laser measurement. Shown is a single displaceable fixation element 16 with vertical abutment surface 18 on the vertical leg 23 for approaching a body site for the purpose of measuring their position. These L-shaped fixation elements 16 are displaceable in each direction and rotatable the desired distances can either be read directly on a coordinate system on the couch, or the respective distances are taken with applied scales and recorded. In their lying leg 17, one or more permanent magnets are inserted, and the couch contains a magnetizable film, so that the fixation elements 16 in each position a sufficient adhesive force apply, so that a body position can be kept for a while to remove all mass at rest. As an alternative to this, the lying legs 17 of the fixation elements 16 can also be clamped to the edge area of the couch 1 by means of a quick-release fastener, similar to a screw clamp, in order to prevent displacement during the recording of the measurements or during the subsequent imaging procedure. For example, there are twelve pieces of these fixation elements 16 on a single patient couch 1, as can be seen from FIG. 5, namely as shown for the following body sites: two fixation elements for the feet, here U-shaped fixation elements as footpegs 6, two Elements for the hip joints, two for the pelvic bone, two elements for the shoulders and two fixation elements for the two sides of the head, each consisting of an L-shaped body. Instead of an L-shaped fixation element, of course, a differently shaped fixation element can be used, such as a cuboid, a rectangular block (cube), or an angle element with differently shaped foot and a stop surface with a different contour.
    In Fig. 7, a passenger bed 1 is shown in side view with a fixation element 16 with a vertical stop surface 18 and in addition a horizontally extending, downwardly directed abutment surface 19 for measuring the height of certain body parts. By means of this belonging to the detection device fixation element 16, the height of the body parts of interest can be measured above the level of the couch 1, ie the height of the uppermost point of the pelvic bone, the hip joint, the kneecaps, the shoulders and the head. In this fixation element 16 shown, the permanent magnets 20 are located in the lying leg 17 or foot. The height-adjustable mounted on the vertical leg block 21 is used with its flat bottom 22 for measuring the heights of the body parts. For this purpose, vertical leg 23 is provided with a scale, so that directly the height of the downwardly directed abutment surface 22 is read. In practice, the stop planes are moved from the outside to the relevant body parts until they rest snugly against the measuring points. Above is moved up to the skull with the fixation element, and with other fixation elements 16 is moved from the outside and then from above to the shoulder bone. With further fixation elements 16 is approached from the side of the upper hip bone, ie to the upper end of the pelvic bone from both sides, until these fixation elements 16 find a stop on the hip bone. Thereafter, with the downwardly directed, height adjustable attached to these fixation elements blocks 21 moved down until the horizontal, downwardly directed abutment surfaces 22 abut on the top of the hipbone bones. It is clear that the abutment surfaces do not strike directly against the bone, but lie as close as possible to the overlying tissue, so that they almost feel the bones. Further fixation elements 16 are moved laterally to the knee joints until they strike against the same. And from below fixation elements in the form of footpegs are moved up to the heel bottoms. In this position, all fixation elements 6,16 firmly clamped by means of clamping means, so that they hold the detected posture immovable. Now, the positions of the fixation elements 16 can be accurately measured, for which various methods are applicable - electronically, electromechanically, by laser or by mere reading. It is understood that the fixation elements 16 can also be designed as a slide, which are pushed horizontally from the lying edge along a guide against the body parts, said pushing can be done mechanically by hand, electrically, pneumatically or hydraulically, as on the left shoulder shown in Fig. 5 with the fixation slider element 12, whereby the contact pressure is finely adjustable and repeatable. These fixation elements that can be extended electrically, pneumatically or hydraulically against the center of the couch can be equipped with a laser distance meter for determining the extension distance and the position of the fixation element along the length of the couch.
    Fig. 8 shows a passenger couch 1 with fixation elements 16 of the detection device for determining the height of the upper pelvic bone and the hip joint on the basis of a section showing only the area in which the dashed pelvic bone 24 is located, here from its right side her seen when a person lies supine on the couch 1. The point 25 denotes the highest point in the upper pelvic bone region, as also shown in Fig. 5, and with 26, the joint socket 27 is indicated for the joint ball on the femur. The levels of these points 25,26 can also be determined by approaching stop surfaces 22 from top to bottom. These points or their height above the passenger couch 1 must be measured. Also for this purpose, the detection device, with which therefore the upwardly projecting parts of the body, namely the height of the hip bone left and right lying pelvic bone 24 can be measured. The fixation element 16 is shown here on the left and right, which has a height-adjustable block 21 with a stop surface 22 directed downwards, and these blocks 21 are adjustable in height on the fixation elements 16. So it moves with the fixation elements 16 with the blocks 21 in its uppermost displacement position laterally to the body of the person zoom, which is on the passenger lounger 1 in the supine position. Then, the blocks 21 are shut down until their bottoms 22 abut on the highest elevation of the body part there, such as the pelvic or femoral neck, at the socket 27, as shown in FIG.
    Fig. 9 shows a passenger couch 1 with fixation elements 16 of the detection device with electromechanical technology for determining the height of the upper pelvic bone and the hip joint on the basis of a section showing only the area in which the pelvic bone 24 comes to rest on the right side of the pelvic bone 24 seen. The fixation elements 16 are here equipped on their underside, each with a computer mouse 28 with enclosed track ball 29. This can be determined when moving the fixation elements 16 on this completely flat person couch 1, the horizontal position and capture and display as a coordinate in the computer. So you drive with these fixation elements 16 from a calibrated starting position on the passenger couch 1 from the edge region forth to the body of the person lying down until it strikes with the vertical stop surface 18 at the right place of the body. The integrated computer mouse 28 provides the position via a cable or wirelessly to the associated computer and thus detects exactly the horizontal position of the abutment surface 18. The blocks 21 for the formation of horizontal, downwardly facing abutment surfaces 22 are height-adjustable along rails on the vertical legs 23 of the fixation elements 16 out. At the contact surfaces a computer mouse 28 is also installed, with their enclosed trackball 29 along the stop surface 18, so the inner vertical surface 18 of the fixation element 16 unrolls and thus detects the altitude. The uppermost position of the pad 21 then forms the calibration position for this computer mouse 28.
    It is clear that other methods for effective exact measurement of the various abutment surfaces can be realized. It is important, however, that these positions of the abutment surfaces are actually accurately and reproducibly detected at the abovementioned body locations, be it by optical scanning, by laser distance measurements, or by mechanical or electromechanical measurements. Only by recording these body positions can an image of the effective body position be gained. It becomes obvious whether or not the body is exactly symmetrical with respect to the central axis of the bed, whether one leg is shorter than the other, whether there is an oblique position, namely the hip or shoulder, and whether the hips and shoulders are exactly horizontal rest on the patient bed, or if there is a twist.
    The further findings of the subsequent imaging examination must urgently be interpreted in the light of this body position in order to be able to pursue the causes of the findings more specifically, in a holistic view of the body and its location, not just by analyzing a local, isolated body part.
