Abstract

The invention relates to a PET image reconstruction method and device, and computer equipment. The PET image reconstruction method comprises the steps: obtaining PET scanning data of a scanning object; planning at least one region of interest on the scanning object; acquiring PET sub-scanning data corresponding to the region of interest from the PET scanning data; and reconstructing a PET image according to the PET sub-scanning data. Regions of interest by planning regions of interest, acquiring PET sub-scanning data of a region of interest from the PET scanning data of the full-axial visual field; the PET sub-scanning data is reconstructed independently, the stored PET data can be reduced, the time for reconstructing the PET image is further shortened, and the reconstructed PET image canprovide an accurate reference basis for doctors.

Description

technical field [0001] The invention relates to the field of image reconstruction, in particular to a PET image reconstruction method, device and computer equipment. Background technique [0002] The full name of PET is positron emission computed tomography, which is a metabolic imaging device that reflects the genes, molecules, metabolism and functional status of lesions. The full name of CT is computerized tomography, which is anatomical information imaging, which uses X-rays to perform physical examination on the human body. PET / CT is an organic combination of PET and CT, using the same examination bed and an image workstation. CT needs to provide PET with imaging tissue attenuation information and structural information of fusion images during diagnosis. PET / CT equipment has been widely used in modern medical examination. [0003] The CT scan length of PET / CT equipment with long axial field of view is much longer than that of PET / CT equipment with traditional scanning ...
