[0002] At present, the mainstream single photon emission computed tomography and CT integrated imaging diagnostic equipment (SPECT-CT) in the market all adopt a patient bed structure. During scanning, the bed is moved and raised to the scanning preparation position, and then the bed board is extended from the bed and the patient is sent to the designated scanning position to start scanning. After the scan is completed, the bed board is retracted, the patient bed is lowered, and the patient is evacuated. Due to the patient's own weight, the suspended part of the bed board is bound to fall to a certain extent, and the longer the extended part is, the more obvious the fall is. SPECT-CT has high requirements for the patient's spatial position. If the patient's position is not relatively parallel to the detector surface, it will affect the image quality and diagnostic accuracy.
[0003] Therefore, it is necessary to develop a new type of SPECT-CT bed board support frame that can play a supporting role in the suspended part of the bed board to prevent the bed board from falling without affecting the normal entry and exit of the bed board, thereby improving the accuracy of the image and the accuracy of the diagnosis.

[0027] In view of the existing technical problems, the utility model provides a SPECT examination bed, including a support frame, a bed body, a sliding assembly and a bed board; the support frame supports the bed body; the sliding assembly is arranged between the bed body and the bed board, and through the sliding assembly, the bed board can move in one direction relative to the bed body. The SPECT examination bed of the utility model has the advantages of simple structure and convenient installation, and can effectively prevent the protruding part of the bed board from falling, thereby improving the quality of SPECT images and improving the accuracy of diagnosis.
[0028] The structure of the SPECT examination bed of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It can be understood that the various specific embodiments are not intended to limit the protection scope of the present invention.
[0029] Figure 1 , Figure 2 and Figure 3 They are structural schematic diagrams of a SPECT examination bed from different perspectives of an embodiment of the utility model. Specifically, the SPECT examination bed includes a support frame 10, a bed body 20, a sliding assembly and a bed board 40; the support frame 10 supports the bed body 20; the sliding assembly is arranged between the bed body 20 and the bed board 40, and through the sliding assembly, the bed board 40 can move in a direction relative to the bed body 20, and usually, the moving direction is the extension direction of the bed body 20.
[0030] In some embodiments, the support frame 10 is liftable, and the height of the bed 20 supported by the support frame 10 is adjusted by adjusting the lifting and lowering of the support frame 10, and most importantly, the height of the bed board 40, that is, adjusting the height of the patient lying flat on the bed board, so that the patient is at the detection point of the SPECT device, thereby obtaining the required image data. For example, the support frame may include a plurality of hydraulic lifting rods, and the plurality of hydraulic lifting rods may be adjusted independently or together, so that the bed has a certain angle with the horizontal plane. The support frame 10 may also include at least one lifting motor. The advantage of using a lifting motor as a support frame is that the SPECT examination bed can be provided with a controller and a height locator for sensing the height of the bed body / bed board, and the control output end of the controller can be connected to the control input end of the lifting motor. The controller can generate a lifting motor control signal according to the data of the height locator, thereby driving the lifting motor to achieve control of the height of the bed body / bed board.
[0031] The sliding assembly may include two rows of pulley blocks, each row of the pulley block including a plurality of pulleys 30, such as two or three (see Figure 3 ) or four pulleys. The utility model does not limit the number of pulleys included in the pulley group. Each pulley can be rotatably fixed to the bed body 20 through a support column 31. The two rows of pulley groups are symmetrically arranged relative to the central axis of the bed board 40, such as Figure 1 shown.
[0032] In some embodiments, the plurality of pulleys are evenly distributed in the moving direction, such as Figure 2 As shown, the above structure ensures that the entire bed board thereon is subjected to uniform and stable force. The sliding assembly may also include at least one supporting pulley (not shown in the figure), and the supporting pulley may be arranged on the central axis of the bed board. For example, the sliding assembly may also include a supporting pulley, and in this case, the supporting pulley may be arranged at the center of the central axis of the bed board, that is, a supporting pulley may be arranged at the center of gravity of the bed board when the bed is in the initial state of the inspection bed, so that the bed board has better stability and smoothness when moving.
[0033] Figure 1 In the embodiment, the side of the bed board 40 facing the bed body 20 is arc-shaped; the contact surface of the pulley 30 and the arc-shaped side of the bed board 40 is tangent to the arc-shaped side of the bed board, that is, the rotation axis of the pulley 30 is parallel to the arc-shaped tangent surface of the bed board 40. In actual use, the above structure is obtained by adjusting the position of the rotation axis of the pulley 30 and the support column 31. The side of the bed board 40 facing the bed body 20 is provided with two guide grooves extending along the moving direction of the bed board 40; the pulley 30 is matched with the bottom surface of the guide groove, that is, each row of pulleys slides along a guide groove, thereby making the bed board 40 move relative to the bed body 20 in a set direction. The cross-section of the guide groove can be trapezoidal, and the short side of the trapezoid can limit the detachment of the pulley. Of course, a limiter can be set in the extension direction of the guide groove to limit the movable range of the pulley.
[0034] Furthermore, in order to facilitate the movement of the bed plate and realize automatic control, the SPECT examination bed also includes a driving device connected to the bed plate, and the driving device is used to drive the bed plate to move relative to the bed body. If the SPECT examination bed is provided with a controller, similarly, the control output end of the controller can be connected to the control input end of the driving device, and the controller can control the displacement of the bed plate to realize the control of the movement direction of the bed plate. It should be pointed out that in the technical scheme of the SPECT examination bed of the utility model, each functional device and module unit included therein can correspond to a specific hardware circuit in the integrated circuit structure, so it only involves the improvement of the specific hardware circuit, and the hardware part is not just a carrier for executing control software or computer program, so solving the corresponding technical problems and obtaining the corresponding technical effects do not involve the application of any control software or computer program, that is, the utility model can solve the technical problems to be solved and obtain the corresponding technical effects only by improving the hardware circuit structure involved in these modules and units, and does not need to be assisted by specific control software or computer program to realize the corresponding functions.
[0035] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention.
