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 of used nuclide is longer, so it is easy to prepare and transport. However, due to the limitation of resolution, the anatomical structure cannot be clearly displayed, and the localization of the lesion is 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.

SPECT/CT devices suffer from inaccurate positioning, and when a region of the patient's body is to be scanned, the patient lies on the bed of the device and moves the region of the patient to be examined through the bed to the region between the upper and lower detectors. However, since there is no positioning indication device for the patient between the upper detector and the lower detector, the medical staff can only distinguish the position by naked eyes, which may cause the examination part not to be located at the center of the detection crystal in the vertical direction, and may even cause the examination part to exceed the detection range of the crystal. When the SPECT/CT device is used, after a patient takes or injects a corresponding radiopharmaceutical, the SPECT/CT device detects the condition of a focus by detecting the radioactive substances of the radiopharmaceutical within a certain time; if the imaging fails, the medicine can be taken again for inspection after a long time is needed and the medicine decays to a certain state before, otherwise the taken radiopharmaceutical can interfere with the second imaging; and the radioactive drug has certain harm to human body, and can be used for a plurality of times in a short time, thus having relatively large influence on the human body. The use of SPECT/CT devices requires as precise imaging as possible at one time.
