Description

Technical Field

[0002] In current medical imaging technologies, devices such as CT (computed tomography) and MR (magnetic resonance imaging) all use supine scanning. However, due to the effect of gravity, the body shape of the human body changes in different positions. Some orthopedic diseases can only show typical symptoms in a standing position, and conventional supine medical imaging equipment cannot meet clinical diagnosis needs. Standing medical imaging equipment can achieve full-body scanning of patients in a weight-bearing standing position by lifting and lowering the scanning frame, which can provide physicians with more accurate scanning images of orthopedic diseases such as scoliosis and spinal stenosis in clinical practice.

[0050] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0051] Based on the problems existing in the prior art, the present disclosure provides a standing medical imaging device. Figure 1 is a schematic diagram of a standing medical imaging device provided by an embodiment of the present disclosure, combined with Figure 1 The standing medical imaging device includes: a scanning device, a first supporting device and a second supporting device, the scanning device includes a scanning room 101, a scanning module 102 and a base 103, the first supporting device includes a bottom plate 201 and a first backing plate 202, and the second supporting device includes a first driver 301, a telescopic rod 302 and a second backing plate 303; the scanning module 102 is arranged in the scanning room 101, and the scanning module 102 moves in a direction perpendicular to the base 103; the bottom plate 201 is assembled on the upper surface of the base 103, and the first backing plate 202 is assembled on the mounting surface of the bottom plate 201; the telescopic rod 302 is arranged on the top of the scanning room 101, and the second backing plate 303 is installed on the movable end of the telescopic rod 302, the first driver 301 drives the movable end of the telescopic rod 302 to rise and fall, and the second backing plate 303 follows the telescopic rod 302 to rise and fall.

[0052] like Figure 1 As shown, the scanning device at least includes a scanning room 101, a scanning module 102 and a base 103. In addition, the scanning device also includes a scanning tray 104 and a vertical lifting frame 105. The scanning cavity of the scanning device is the scanning room. The scanning module 102 is arranged in the scanning room 101. The scanning module 102 moves in a direction perpendicular to the base 103. The scanning tray 104 moves along the vertical lifting frame 105. The movement of the scanning tray 104 drives the scanning module 102 to move. By controlling the movement of the scanning tray 104, the scanning module 102 can scan different scanning parts of the patient in the scanning room 101.

[0053] like Figure 1 As shown, the first supporting device includes a base plate 201 and a first back plate 202. The base plate 201 is mounted on the upper surface of the base 103, and the first back plate 202 is mounted on the mounting surface of the base plate 201. When the scanning device scans a patient, the base plate 201 is a supporting plate for the patient to stand on during the scanning, and the first back plate 202 provides support for the patient's legs.

[0054] In a specific embodiment, the height of the first backrest 202 is a preset height, which is determined based on the average knee height of a human body. By setting the height of the first backrest 202 to the average knee height of a human body, the stability and comfort of the patient's standing during the scanning process are increased.

[0055] Continue to see Figure 1The standing medical imaging device further includes a second supporting device, which includes a first driver 301, a telescopic rod 302, and a second supporting plate 303. The telescopic rod 301 is arranged on the top of the scanning room 101, and the second supporting plate 303 is installed on the movable end of the telescopic rod 302. The first driver 301 drives the movable end of the telescopic rod 302 to rise and fall, and the second supporting plate 303 follows the telescopic rod 302 to rise and fall. The first driver 301 receives a control signal, and controls the movable end of the telescopic rod 302 to rise and fall according to the control signal, thereby driving the second supporting plate 303 to rise and fall.

[0056] As a specific embodiment, when the scanning range of the scanning module of the scanning device is the head range, the telescopic rod 302 is controlled to move so that the distance between the second support plate 303 close to the bottom plate 201 and the bottom plate 201 of the first supporting device is greater than the height of the scanned patient; when the scanning range of the scanning module of the scanning device is the chest and abdomen range, the telescopic rod 302 is controlled to move so that the distance between the second support plate 303 close to the bottom plate 201 and the bottom plate 201 of the first supporting device is greater than the height of the chest of the scanned patient; when the scanning range of the scanning module of the scanning device is the ankle range, the telescopic rod 302 is controlled to move so that the distance between the second support plate 303 close to the bottom plate 201 and the bottom plate 201 of the first supporting device is greater than the height of the ankle of the scanned patient, thereby avoiding the formation of an eccentric structure within the scanning range of the scanning module and providing maximum support for the patient.

[0057] The standing medical imaging device provided by the embodiment of the present disclosure is provided with a first supporting device and a second supporting device in the device. The first supporting device includes a bottom plate and a first back plate. The bottom plate is mounted on the upper surface of the base, and the first back plate is mounted on the mounting surface of the bottom plate. The second supporting device includes a first driver, a telescopic rod, and a second back plate. The telescopic rod is arranged on the top of the scanning room, and the second back plate is mounted on the movable end of the telescopic rod. The first driver drives the movable end of the telescopic rod to rise and fall, and the second back plate follows the rise and fall of the telescopic rod. When the scanning device scans the patient, the bottom plate of the first supporting device is a supporting plate on which the patient stands during the scanning, and the first back plate provides support for the patient's legs. The second supporting device adjusts the height of the second back plate through the first driver and the telescopic rod according to the scanning range of the scanning device of the scanning device. On the basis of providing support for the patient, the formation of an eccentric structure within the scanning range of the scanning module is avoided, thereby achieving consistent attenuation in all directions within the scanning range, ensuring image quality, and ensuring accurate diagnosis.

[0058] As a specific implementation, the first driver 302 includes a first motor and a lead screw, the lead screw is connected to the movable end of the telescopic rod, and the first motor drives the movable end of the telescopic rod to rise and fall through the lead screw.

[0059] Specifically, the first driver is composed of a first motor and a screw, the first driver is electrically connected to the control module, the first driver receives a first control instruction sent by the control module and drives the movable end of the telescopic rod to rise and fall through the first motor and the screw, thereby realizing automatic lifting and precise adjustment of the second support plate.

[0060] Based on the above embodiment, the standing medical imaging device further includes a third supporting device, such as Figure 1 , Figure 2A and Figure 2B As shown, the third supporting device includes a second driver 401, a guide rail 402 and a support body 403, and the support body 403 includes a first support body 403A and a second support body 403B; the guide rail 402 is installed on the upper surface of the base 103, and the second support body 403B is installed on the guide rail 402, and the second driver 401 drives the second support body 403B to move along the guide rail 402 so that the first support body 403A and the second support body 403B form a hollow cylinder; the vertical projection of the hollow cylinder formed by the first support body 403A and the second support body 403B on the base is located within the vertical projection of the scanning module on the base.

[0061] Specifically, by providing a third support device in the standing medical imaging equipment, when the scanning device is in a scanning state, the first support body 403A and the second support body 403B in the third support device form a hollow cylinder that can surround the patient. The patient can hold the first support body 403A and / or the second support body 403B to avoid falling. The first support body 403A and the second support body 403B can support the patient. In addition, since the first support body 403A and the second support body 403B form a hollow cylinder that surrounds the patient, an eccentric structure can be avoided from being formed within the scanning range of the scanning module, thereby achieving consistent attenuation in all directions within the scanning range, ensuring image quality, and ensuring accurate diagnosis.

[0062] In the specific implementation process, the guide rail 402 of the third support device is installed on the upper surface of the base 103, and the second support body 403B is installed on the guide rail 402. The guide rail 402 provides a fixed track for the movement of the second support body 403A to ensure the smoothness and accuracy of the movement of the second support body 403B. The second driver 401 drives the second support body 403B to move along the guide rail 402, so that the second support body 403B and the first support body 403A form a hollow cylinder.

[0063] Specifically, the first support body 403A is fixed to the upper surface of the base 103. When the scanning module of the scanning device is in a non-scanning state, the first support body 403A and the second support body 403B overlap. When the scanning module of the scanning device enters a scanning state from a non-scanning state, the control module outputs a second control instruction to the second driver 401. The second driver 401 drives the second support body 403B to move along the guide rail 402 to a side relative to the first support body 403A according to the received second control instruction, forming a hollow cylinder with the first support body 403A.

[0064] As a preferred embodiment, the first support body 403A is disposed on the rear side of the first back plate.

[0065] By arranging the first support body behind the first back plate, when the scanning module of the scanning device is in a non-scanning state, the second support body 403B overlaps with the first support body 403A and is located behind the patient, and the channel in front of the scanning position is opened for the patient to enter.

[0066] In the specific implementation process, continue to refer to Figure 2A The third support module also includes a rack 404, and the second driver 401 includes a second motor and a gear. The rack 404 is installed on the outer surface of the second support body 403B and meshes with the gear in the second driver 401. The second motor drives the gear 401 to move so that the gear drives the rack to move.

[0067] When the scanning module of the scanning device changes from a non-scanning state to a scanning state, the second support body 403B can move toward the front of the patient along the guide rail 402 through the drive of the second driver 401, and the two groups of support bodies surround the front, sides and back of the patient to form a surrounding support structure.

[0068] The process of the second driver 401 driving the second support body 403B to move along the guide rail 402 is completed based on the cooperation of the second motor, the gear and the rack installed on the outer surface of the second support body, wherein the second motor drives the gear to rotate, the gear drives the rack to move, and the rack drives the second support body to move along the guide rail.

[0069] Based on the above embodiment, the height of the support body is set to meet the following requirements:

[0070] ,

[0071] Wherein, h is the height of the support body, R is the inner diameter of the scanning module, and H is the maximum scanning height of the scanning module.

[0072] Specifically, assuming that the inner diameter of the scanning module in the scanning device of the standing medical imaging equipment is R, and the maximum scanning height is H, according to the "Human Body Dimensions of Chinese Adults" (GB / T 10000-2023), in order to ensure the safety of most patients, the patient's height is set to 1900mm, the shoulder width is 450mm, and the finger thickness is 20mm; when the patient falls, in order to enable the patient to lean on the third support device to avoid the patient's head colliding with the scanning device or falling to the ground, it is assumed that the patient's body is always in a straight line, and the patient's head collides with the scanning device, that is, the distance between the farthest point of the head and the rotation center is equal to half of the inner diameter of the scanning device. According to the Pythagorean theorem, h should be greater than .

[0073] At the same time, in order to ensure the scanning continuity of the scanning module, h should be greater than H. Therefore, the height of the support body of the third supporting device should satisfy the following formula:

[0074] ,

[0075] The inner diameter of the first support body and the inner diameter of the scanning module satisfy:

[0076] ,

[0077] Wherein, R is the inner diameter of the scanning module, r1 is the inner diameter of the first support body, and d is the thickness of the support body.

[0078] In order to adapt to the body size of most patients and prevent them from feeling claustrophobic during scanning, the inner diameter of the first support body r1 should be greater than 600 mm. However, the inner diameter r1 of the first support body cannot be too large. It is necessary to ensure that there is a certain space between the support body and the scanning frame. Therefore, the inner diameter of the first support body and the inner diameter of the scanning module should satisfy the following formula.

[0079] ,

[0080] The relationship between the inner diameter of the first support and the inner diameter of the second support satisfies:

[0081] ,

[0082] Wherein, r1 is the inner diameter of the first support body, r2 is the inner diameter of the second support body, and d is the thickness of the support body.

[0083] In order for the second support body to be able to move on the guide rail to realize the opening and closing of the third support device, the inner diameter r1 of the first support body should be slightly smaller than the inner diameter r2 of the second support body. When the attenuation coefficient of the material used for the support body and the thickness are small, the difference in radiation attenuation between the two can be ignored. d is a fixed value, and d is generally selected between 10mm and 25mm.

[0084] On the basis of the above embodiment, the vertical projections of the first backing plate 202 and the second backing plate 303 on the base are arc-shaped.

[0085] In order to better fit the patient's body shape, the vertical projections of the first backboard and the second backboard on the base are set to be arc-shaped, so that when the human body is supported by the first backboard and the second backboard, it can better fit the patient and make the patient's standing stability better.

[0086] Based on the above embodiments, Figure 3 is a structural schematic diagram of another standing medical imaging device provided by an embodiment of the present disclosure, such as Figure 3 As shown, the standing medical imaging device further includes a fourth supporting device 500, and the fourth supporting device 500 is arranged on the bottom plate of the first supporting device.

[0087] A fourth supporting device is arranged on the first supporting device, the fourth supporting device is a rectangular parallelepiped, the height of the fourth supporting device is the same as the height of the first back plate in the first supporting device, and the fourth supporting device is arranged on the first supporting device when the patient performs an ankle scan. The patient stands on the fourth supporting device, so that the scanning module scans the ankle, and there is no eccentric structure within the scanning range of the ankle scan, thereby achieving consistent attenuation in all directions within the scanning range, ensuring image quality, and ensuring accurate diagnosis.

[0088] It should be noted that in the above embodiment, the bottom plate in the first supporting device may be made of metal alloy materials, such as stainless steel, aluminum alloy, etc., because it needs to bear the entire weight of the patient's body;

[0089] The first backing plate in the first supporting device and the second backing plate in the second supporting device can be made of materials with high hardness and low relative density. At the same time, since they are in direct contact with the patient, the selected materials should have good biocompatibility, such as carbon fiber.

[0090] The support body in the third support device is within the scanning range, which plays a supporting and protective role for the patient who falls. At the same time, considering the psychological pressure brought by the closed material to the patient, a polymer transparent material with a relatively small attenuation coefficient and moderate hardness, such as polystyrene, polymethyl methacrylate, etc., or a composite transparent material, such as acrylic, etc., can be selected;

[0091] The fourth supporting device also needs to bear the full weight of the patient's body, but since it needs to be carried back and forth, an alloy material with high hardness and relatively low relative density can be selected.

[0092] On the basis of the above-mentioned embodiments, the standing medical imaging equipment provided by the embodiments of the present disclosure further includes a control module, which is electrically connected to the first driver and the second driver respectively, and the control module outputs a first control instruction to the first driver, and the control module outputs a second control instruction to the second driver. Under the action of the first control instruction output by the control module, the first driver drives the movable end of the telescopic rod to rise and fall, thereby causing the second back plate to rise and fall with the telescopic rod, and under the action of the second control instruction output by the control module, the second driver drives the gear to rotate, and the gear rotation drives the rack to move, and the rack movement drives the second support body to move along the guide rail.

[0093] On the basis of the above embodiments, the present disclosure further provides a method for controlling a standing medical imaging device. The method for controlling a standing medical imaging device provided by the present disclosure is applied to the standing medical imaging device described in any of the above embodiments. Figure 4 is a flow chart of a method for controlling a standing medical imaging device provided by an embodiment of the present disclosure, such as Figure 4 As shown, the control method of the standing medical imaging equipment includes:

[0094] S110 . After receiving the information that the patient has entered the scanning room, determine the scanning range of the target object.

[0095] S120 , outputting a first control instruction to the first driver according to the scanning range of the target object, so as to control the first driver to drive the second support plate to move to the target position.

[0096] It should be noted that the target position is determined based on the scanning range of the target object. As an exemplary example, when the scanning range of the scanning module of the scanning device is the head range, the telescopic rod 302 is controlled to move so that the distance between the second support plate 303 close to the bottom plate 201 and the bottom plate 201 of the first supporting device is greater than the height of the scanned patient. That is, the target position is such that the distance between the second support plate 303 close to the bottom plate 201 and the bottom plate 201 of the first supporting device is greater than the height of the scanned patient, thereby avoiding the formation of an eccentric structure within the scanning range of the scanning module and providing support to the patient to the greatest extent.
