Background

SPECT, an instrument for achieving in vivo functional and metabolic imaging by labeling drugs with single photon nuclides, is one of the basic instruments for nuclear medicine imaging, and is currently equipped in most local hospitals and plays an important role in imaging diagnosis of diseases. It features that it can reflect the information about blood perfusion and metabolism of tissue and organ, and the half-life period of the used nuclide is longer, so it is easy to prepare and transport, so it has low cost and is easy to popularize.

Due to the limitation of resolution, SPECT cannot clearly display anatomical structures, which makes localization of lesions difficult. At present, SPECT/CT fusion models are generated, functional images of SPECT and diagnostic CT images can be fused accurately, and the defects of SPECT in anatomical positioning and resolution are overcome. The SPECT/CT equipment is used, functional metabolic imaging and anatomical imaging can be obtained through one-time scanning of a patient, the special advantages are achieved for focus positioning and disease diagnosis, a doctor is helped to reduce misdiagnosis rate, the integral diagnosis and treatment level of a medical institution is improved, and the SPECT/CT equipment has a great application prospect.

The positioning device of the current medical imaging equipment needs to manually adjust the position of the medical imaging equipment in the using process, but the adjusting speed is slow; or the patient needs to move and cooperate on the bed surface, and the patient needs to adjust and position for multiple times, so that the medical imaging equipment has certain limitation in the process of detection, positioning and use; meanwhile, because the ray has certain harm to the human body, when the patient is irradiated, the patient needs to be protected from radiation by manual operation except the detection area, and time and labor are wasted. To a certain extent, the work efficiency when using medical imaging equipment to observe has been reduced, and medical imaging equipment does not possess better scope nature adjustability for the doctor has a little inconvenience at the in-process that uses medical imaging equipment.

10. A method of using the detection localization system of the SPECT/CT apparatus of any one of claims 1 to 9, comprising the steps of:

s1: when the device is used, a patient lies on the bed board (4), if the detector (6) is not aligned with a region to be detected and scanned by the patient, the displacement mechanism in the shell (7) works to simultaneously perform displacement adjustment on the patient on the bed board (4) and the detector (6) on the mounting plate (5), and the range plate (8) on the mounting plate (5) can effectively display the region to be detected and scanned on the patient during adjustment;

s2: the output end of a second motor (901) drives a rotating shaft (902) to rotate by controlling the second motor (901), so that a main bevel gear (9031) and an auxiliary bevel gear (9032) on an L-shaped plate (903) at the position of the rotating shaft (902) are meshed, a first screw rod (904) and a second screw rod (905) are rotated, if a bed plate (4) is driven to move right when the first screw rod (904) rotates, a mounting plate (5) is driven to move left when the second screw rod (905) rotates, in the process, the mounting plate (5) drives a swinging rod (3) to slide on a rotating rod (201), and the swinging rod (3) drives a second sliding block (402) to slide in a second sliding groove (4021), so that a patient on the bed plate (4) and a detector (6) on the mounting plate (5) are close to each other;

s3: if the distance between the detecting instrument (6) and a patient on the bed plate (4) needs to be increased or decreased, the third motor (11) is controlled to operate, the output end of the third motor (11) drives the third screw rod (111) to rotate, and due to the fact that the thread lines of the two ends of the third screw rod (111) are opposite, when the third screw rod (111) rotates, the moving plates (112) on the two sides are close to or far away from each other relatively, the moving plates (112) drive the L-shaped plate (903) to move, the L-shaped plate (903) drives the main bevel gear (9031) to move up or down on the rotating shaft (902), and then the patient on the bed plate (4) and the detecting instrument (6) on the mounting plate (5) are far away from or close to each other simultaneously;
