Specific embodiments of the present application are described below with reference to the accompanying drawings.
Before describing the embodiments of the present application, the constitution and the existing problems of the conventional vertical medical imaging apparatus will be briefly described with reference to fig. 1 by taking a conventional CT apparatus as an example. The vertical CT apparatus shown in fig. 1 includes a vertical support frame 10, a scanning device (including a CT slip ring and a detector assembly) 20 supported by the support frame 10, and a back plate 30 for fixedly detecting the position of a person. The distance from the bottom surface of the scanning device to the light plane is indicated with h1 in fig. 1, which distance is for example about 500mm. When the scanning device moves vertically to the lowest position, the bottom surface of the scanning device is flush with the standing surface of the person to be detected, the light plane of the scanning device is positioned at the position of the leg (such as the lower leg) of the person to be detected, and the light plane of the scanning device cannot scan the body part of the person to be detected in the range of h 1. In addition, the rigidity of the backup plate 30 in the existing CT apparatus is low, and when a person leans against the backup plate 30, the backup plate 30 is easy to generate artifacts due to back and forth shaking.
The application aims to provide a human tester support system suitable for vertical medical imaging equipment, which can scan the whole body of a tester, is designed to be friendly to the tester, and is safe and reliable. Meanwhile, the application also provides a related supporting system using method and medical imaging equipment.
Fig. 2 shows a support system 1 for a person under examination according to an embodiment of the application, which may be used in a vertical CT device or other suitable vertical medical imaging device, for example an MRI device, a PET-CT device, a CT-MR or a PET-MR device. The inspection person support system 1 of fig. 2 includes a horizontal movement mechanism 100 for horizontally moving an inspection person, a vertical movement mechanism 200 for vertically moving the inspection person, and a fence 300 for fixing the position of the inspection person. The horizontal moving mechanism 100 is positioned at the bottom, the vertical moving mechanism 200 and the leaning board 300 are installed on the horizontal moving mechanism 100, the inspector can stand on the vertical moving mechanism 200, and the back depends on the leaning board 300. The horizontal moving mechanism 100 drives the vertical moving mechanism 200 and the backup plate 300 to move horizontally, and the vertical moving mechanism 200 drives the inspector to move vertically, so that the movement of the inspector in the horizontal and vertical directions is realized.
Specifically, the horizontal moving mechanism 100 may be fixed to a base of the image room, including a first driving assembly 110 and a supporting device 130 (refer to fig. 3) horizontally movable by driving of the first driving assembly 110, the supporting device 130 serving to support the vertical moving mechanism 200 and the armrest 300, for example, configured as a support plate. As described above, the horizontal moving mechanism 100 can drive the inspector to move horizontally to adjust the position to be scanned of the inspector to coincide with the ISO center of the scanning apparatus. Further, the horizontal moving mechanism 100 drives the detecting person to be located at an eccentric position relative to the scanning device, the visual feeling of the detecting person is more comfortable, the feeling that the scanning device is very imminent does not exist, and the psychological condition and emotion are more stable.
The vertical movement mechanism 200 is fixed to the supporting device 130 of the horizontal movement mechanism 100, and includes a second driving assembly 210 and a carrying device 280 (refer to fig. 3) vertically movable by driving of the second driving assembly 210, the carrying device 280 being for carrying a person to be detected, for example, being configured as a standing board. The vertical moving mechanism 200 can adjust the position of the sole of the inspector reaching above the lowest light plane of the scanning device, so that the inspector can complete whole-body scanning by one-time positioning. The first and second drive assemblies 110 and 210 are, for example, motor drive assemblies, pneumatic or hydraulic drive assemblies, as will be described in more detail below.
The fence 300 is also mounted to the supporting device 130 (please refer to fig. 3) of the horizontal movement mechanism 100, and the vertical movement mechanism 200 is vertically movable with respect to the fence 300, so that a inspector standing on the vertical movement mechanism 200 can vertically move with respect to the fence 300. In other embodiments, the fence 300 may be mounted to the carrier 280 of the vertical movement mechanism 200, with the fence 300 being moved vertically in unison by the vertical movement mechanism 200, in which case the relative positions of the vertical movement mechanism 200 and the fence 300 are fixed. The fence 300 can realize the support of the inspector, and simultaneously realize the positioning and fixing of the inspector in the horizontal direction. As shown in fig. 2, each of the left and right sides of the armrest 300 has a plurality of grip portions 330 arranged in the longitudinal direction of the armrest 300, the grip portions 330 being for the human subject to grasp autonomously to allow the human subject to keep his body stable in a posture adapted to him/herself.
The inspection person supporting system can complete whole-body scanning of a standing inspection person through one-time positioning without image splicing; the human detection support system is more friendly to human detection, and the gripping parts on the lateral sides of the leaning plate allow human detection with different body types to autonomously select positioning postures; the horizontal moving structure eccentrically positions the detecting person relative to the scanning device, and the eccentric position is very friendly to the detecting person, is beneficial to stably detecting the emotion of the person, ensures the safety of the detection process and has more accurate detection data.
Other aspects of the application will be described with continued reference to the drawings.
According to the present application, the grip 330 of the armrest 300 is configured as an elongated hole extending in the longitudinal direction of the armrest 300, which may be a monolithic elongated hole or a plurality of oblong holes aligned in the longitudinal direction (refer to fig. 2). The sides of the grip 330 in the form of an elongated hole provide a guide for the hand of the inspector, which can slide along the longitudinal sides of the grip 330 while gripping the grip 330 when the vertical movement mechanism 200 drives the inspector to move vertically, so that the inspector keeps his body stable by means of the grip 330 when moving vertically. The length of the gripping portion 330 in the form of an elongated hole may be between 30 and 80 cm.
With continued reference to fig. 4 and 5, the specific structure of the fence 300 is described. As shown in FIG. 4, the back plate 300 is generally rectangular in shape and is high enough for a person of different heights to rest on and still support the entire height of the person after the person moves vertically upward. The fence 300 is secured to the support 130 or the carrier 280 by sheet metal and fasteners (e.g., screws). The bottom 311 of the armrest 300 is reduced in width relative to the body of the armrest 300 at a position (within a distance of the light plane and the ground) near the horizontal movement mechanism 100 such that a receiving portion 312 is formed between the bottom 311 of the armrest 300 and the body, the space provided by the receiving portion 312 being adapted to receive components of the vertical movement mechanism 200, preventing movement interference between the armrest 300 and the vertical movement mechanism 200. The front of the bottom 311 has a reinforcement member 317 for reinforcing the armrest 300, and the back of the bottom 311 has a reinforcement member 318, as shown in fig. 5. The reinforcement members 317 and 318 are, for example, metal or carbon fiber reinforcement ribs or reinforcement plates, which may also serve as mounting members for the fence 300 to the supporting device 130 or the carrying device 280.
As shown in fig. 5, the armrest 300 has a concave lateral structure composed of an arc-shaped front panel 310 and a curved rear panel 320 fixed to each other at the sides, which are made of, for example, carbon fiber skin, the arc-shaped front panel 310 being well fitted and accommodating the body of the person under examination, the curved rear panel 320 providing a stable and comfortable back support. The side 321 of the rear panel 320 is located inside the side 313 of the front panel 310, and the side 321 of the rear panel 320 is configured to be gradually inclined toward the front panel 310, thereby being combined with the side 313 of the front panel 310 in a gradually fitting manner to form a whole. This configuration can significantly reduce stress concentration at the connection portion of the front panel 310 and the rear panel 320, so that the force of the inspector against the fence 300 is uniformly distributed over the entire fence 300. The plurality of grip portions 330 are disposed on the side 313 of the front panel 310, the side 321 of the rear panel 320 is located inside the grip portions 330, the region covered by the rear panel 320 is a bearing region, and the region of the grip portions 330 is a grip region. Advantageously, in order to provide stable positioning for the inspector and to promote safety during vertical movement, the front panel 310 is provided with inspector positioning strips 340 extending in the longitudinal direction of the armrest 300 on the inner side of the grip 330, and as shown in fig. 4, the intervals D of the inspector positioning strips 340 are determined to be equivalent to the body width of the inspector. The inspector's body is accommodated inside the inspector positioning belt 340 while the inspector rests on the back plate 300 and during the vertical movement, and the inspector positioning belt 340 prevents the inspector from shaking left and right and provides guidance for the inspector.
With continued reference to fig. 5, there is illustrated an internal structure between the front panel 310 and the rear panel 320 of the fence 300, the internal structure including a core member 315, the core member 315 acting as an internal support structure that provides sufficient structural rigidity to the fence, such as an aluminum alloy inlay member. The internal structure may also include an internal cushioning structure, such as a foam member, for providing a moderate structural resilience to provide comfortable support for the person under inspection.
With continued reference to fig. 6, a specific structure of the vertical movement mechanism 200 of the inspection person support system 1 according to the present application will be described. The second drive assembly 210 of the vertical movement mechanism 200 is a servo motor assembly, and the carrier 280 is configured as a lifting top plate for a person to be detected to stand. The second driving assembly 210 may be composed of a servo motor 212, a speed reducer 213, a coupling 214, a screw 215 and a screw 217, wherein the servo motor 212 is connected to the speed reducer 213 to reduce speed, and then is connected to the screw 215 through the coupling 214, the screw 215 is connected to the screw 217, and the screw 215 rotates to drive the screw 217 to move transversely. The end of the screw 215 is fixed to the bottom plate 270 by the fixing block 211, the middle of the screw 215 is supported on the bottom plate 270 by the supporting block 216, and the bottom plate 270 is fixed to the horizontal movement mechanism 100.
