[0002] With the increasing incidence of prostate cancer, the demand for prostate cancer diagnosis and treatment is growing. Currently, prostate diagnosis mainly includes PSA-specific testing, imaging examinations, and biopsies. In the imaging diagnosis of prostate cancer, gamma cameras can be used to perform prostate-specific membrane antigen (PSMA) imaging, which helps to detect and locate metastatic lesions of prostate cancer.

[0003] A gamma camera, also known as a scintillation camera, is a stationary instrument used to image the distribution of radioactive nuclides. It is used to image radionuclides that emit gamma radiation statically and dynamically. It was widely used in early drug development and nuclear medicine imaging, such as for analyzing the distribution of radiolabeled nuclides in the human body.

[0004] Currently available prostate cancer imaging equipment typically requires patients to lie on a bed or flat surface for imaging. However, the patient's imaging posture often varies. When the imaging posture needs to change at a certain angle from the lying position, the patient often needs to adjust repeatedly according to their needs, which can easily lead to poor communication between doctors and patients and cause some inconvenience for some patients with mobility impairments.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] like Figure 1 and Figure 2As shown, a prostate cancer imaging device based on nuclear medicine imaging includes: a base 1, a bed board 11 disposed on top of the base 1, and an imaging mechanism 2 disposed on top of the bed board 11; a tilt adjustment component is disposed between the base 1 and the bed board 11.

[0028] The tilt adjustment assembly includes: a semi-cylinder 3 fixed to the top of the base 1, a semi-worm gear 31 fixed to the top of the semi-cylinder 3, and several fixed plates 32 fixed to the bottom of the bed board 11; a first servo motor 33 is fixed to one side of the fixed plate 32, and a worm gear 34 is fixed to the output end of the first servo motor 33; several fixed rings 35 are fixed to the top of the base 1 at both ends of the semi-cylinder 3, and several swing blocks 36 are fixed to the bottom of the bed board 11; the top of the fixed rings 35 is provided with a limit groove 37, and the bottom of the swing blocks 36 is provided with a limit member for limiting the swing block 36 when it slides along the fixed rings 35.

[0029] It should be noted that the sides of the worm gear 34 near both ends are rotatably connected to the inner sides of several fixed plates 32, and the sides of the worm gear 34 mesh with the sides of the semi-worm gear 31; the bottom of the swing block 36 overlaps with the top of the fixed ring 35, and the swing block 36, fixed ring 35, limiting groove 37 and semi-worm gear 31 are all coaxially arranged with the semi-cylinder 3; when the patient lies on the bed board 11, and the patient's imaging posture needs to change at a certain angle from the supine posture, the first servo motor 33 is started to drive the worm gear 34 to rotate between several fixed rings 35. Through the meshing of the sides of the worm gear 34 with the sides of the semi-worm gear 31, the swing block 36 can swing along the sides of the fixed ring 35 under the cooperation of the limiting member and the limiting groove 37, so that the bed board 11 can be tilted relative to the base 1 at a certain angle, thus eliminating the need for the patient to adjust the supine posture to complete the required imaging posture. At the same time, it provides convenience for patients with limited mobility, thereby improving the practicality of the device.

[0030] like Figure 3 As shown, the limiting component includes: a fixing strip 4 fixed to the bottom of the swing block 36, and a limiting piece 41 fixed to the bottom of the fixing strip 4; the side of the fixing strip 4 is slidably connected to the inner side of the limiting groove 37, and the top of the limiting piece 41 overlaps with the inner side of the fixing ring 35.

[0031] It should be noted that the fixing strip 4 and the limiting piece 41 are located in the middle of the swing block 36. When the swing block 36 swings left and right along the side of the fixing ring 35, the fixing strip 4 at the bottom of the swing block 36 will slide inside the limiting groove 37, and the limiting piece 41 at the bottom of the fixing strip 4 will swing synchronously along the inside of the fixing ring 35, thereby playing the role of limiting the sliding.

[0032] The top of the bed board 11 is provided with several hand straps 5 and several leg straps 51 for the patient to lie on the top of the bed board 11 and to limit the posture.

[0033] It should be noted that the hand straps 5 and leg straps 51 are both connected by Velcro. When the patient lies on the bed board 11, the hand straps 5, with the help of the Velcro, can restrain the patient's hands, and the leg straps 51, with the help of the Velcro, can restrain the patient's legs, thereby securing the patient to the top of the bed board 11.

[0034] like Figure 2 and Figure 3 As shown, a translation component is provided on one side of the imaging mechanism 2. The translation component includes: an arc-shaped rod 6 fixed to one side of the base 1, a fixed frame 61 fixed to one side of the arc-shaped rod 6, and a second servo motor 62 fixed to one side of the fixed frame 61. The fixed frame 61 is provided with a threaded rod 63 and a slide rail 64. A moving block 65 and a slider 66 are fixed on the side of the imaging mechanism 2 facing the fixed frame 61.

[0035] It should be noted that the sides of the threaded rod 63 near both ends are rotatably connected to the inner side of the fixed frame 61, the output end of the second servo motor 62 is fixed to one end of the threaded rod 63, and one side of the slide rail 64 is fixed to the inner side of the fixed frame 61; the inner side of the moving block 65 is threadedly connected to the side of the threaded rod 63, and one side of the slider 66 is slidably connected to one side of the slide rail 64; when imaging, the second servo motor 62 is started to drive the threaded rod 63 to rotate, which can drive the moving block 65 threadedly connected to the side of the threaded rod 63 to move along the length of the fixed frame 61, thereby driving the imaging mechanism 2 to move synchronously. At the same time, the slider 66 on one side of the imaging mechanism 2 will slide along one side of the slide rail 64, which can play a role in limiting the sliding, thus enabling better adjustment according to the imaging area required by the patient, without requiring the patient to move their body, thereby further improving the practicality of the device.

[0036] A number of storage boxes 7 for storing items are provided on one side of the base 1, and a handle 71 is fixed on one side of the storage box 7. The storage boxes 7 make it easy to store medical supplies inside the storage boxes 7. By holding the handle 71, the storage box 7 can be pulled out from one side of the base 1.

[0037] When this invention is in use, after the patient lies on the bed board 11, the hand straps 5, with the help of Velcro, can restrain the patient's hands, and the leg straps 51, with the help of Velcro, can restrain the patient's legs, thereby stabilizing the patient on the top of the bed board 11. When the patient's imaging posture needs to change at a certain angle from the supine posture, the first servo motor 33 is activated to drive the worm gear 34 to rotate between several fixed rings 35. Through the engagement of the side of the worm gear 34 with the side of the half-worm wheel 31, the swing block 36 can swing along the side of the fixed ring 35 with the cooperation of the limiting member and the limiting groove 37, so that the bed board 11 can be adjusted relative to the base 1. The device allows for precise tilt adjustment, eliminating the need for the patient to adjust their lying position to achieve the desired imaging posture. This provides convenience for patients with limited mobility. During imaging, the second servo motor 62 is activated to rotate the threaded rod 63, which in turn moves the moving block 65, which is threaded to the side of the threaded rod 63, along the length of the fixed frame 61. This, in turn, moves the imaging mechanism 2 synchronously. Simultaneously, the slider 66 on one side of the imaging mechanism 2 slides along one side of the slide rail 64, which serves as a limiting slide. This allows for better adjustment of the imaging area required by the patient, without requiring the patient to move their body, thus further improving the practicality of the device.
