Abstract

The invention belongs to the field of medicine and discloses a gating signal determination method and a gating signal determination device. The method includes: acquiring single photon position information detected in sub-periods of preset duration in a detection period by PET (positron emission tomography) equipment, wherein the single photon position information includes detection crystal identifiers and axial position identifiers; respectively determining single photon distribution information corresponding to each sub-period according to the single photon position information corresponding to each sub-period; determining gating signals according to the single photon distribution information corresponding to each sub-period, and performing PET image reconstruction on the basis of the gating signals. By adoption of the gating signal determination method and the gating signal determination device, diagnosis system cost can be reduced.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a method and device for determining a gating signal. Background technique [0002] In the field of medicine, PET / CT (positron emission tomography / computed tomography, positron emission tomography / computed tomography) equipment can be used for early diagnosis of human or animal tumors, heart system diseases and nervous system diseases, that is, through The PET / CT equipment scans the scanned image to determine the location of the lesion. However, during PET imaging, because the imaging process has a certain length of time, the respiratory movement or heart beat of the scanned object periodically shifts the tissue where the lesion occurs (such as the lung) in space, resulting in blurring of the obtained PET image. Difficult or impossible to identify small lesions in PET images. [0003] In order to eliminate the blurring of PET images caused by respiratory motion, gating technology is ofte...
