The invention provides a radiation residue scanning device and system and relates to the technical field of nuclear medical imaging; the device comprises a plurality of CZT (CdZnTe) detectors, a plurality of data processing units, a plurality of window acquisition circuits, a plurality of counting units and a processor; the CZT detectors are in one-to-one corresponding connection with the data processing units; the data processing units are in one-to-one corresponding connection with the window acquisition circuits; the window acquisition circuits are in one-to-one corresponding connection with the counting units, wherein each window acquisition circuit includes a plurality of acquisition modules connected in parallel, each counting unit includes a plurality of counting subunits in one-to-one corresponding connection with acquisition window modules, and the processor is connected with the counting units. Subsequent circuitry is modified for the CZT detectors, more acquisition windows are added at the premise of reducing the width of acquisition windows, and the problems of low detection efficiency and low spatial resolution is solved.

Description

technical field [0001] The invention relates to the technical field of nuclear medicine imaging, in particular to a radiation residue scanning device and system. Background technique [0002] At present, high-energy elements are more and more widely used in nuclear medicine, such as iodine-131 element, especially the application of iodine-131 to thyroid diseases, such as iodine-131 diagnostic whole-body imaging, iodine-131 whole-body imaging after treatment, Iodine-131 removes residual thyroid tissue after thyroid cancer surgery and treats recurrent and metastatic tissue, etc., with remarkable curative effect, safety and convenience, so it is the fastest-growing radionuclide treatment item in my country. [0003] Patients treated with iodine-131 need to monitor the residual radiation dose in order to better observe and analyze the condition. At present, nuclear medicine uses γ-ray imaging technology to obtain images of the distribution of iodine-131 in the human body. Since...
