Abstract

The invention relates to a PET scanned data scattering correction method and device, computer equipment and a readable storage medium, wherein the PET scanned data scattering correction method comprises the following steps: acquiring PET scanned data of an scanned object in a first time (T1); determining start time of scattering correction within the first time (T1) according to the volume of thePET scanned data; and carrying out scattering correction on the PET scanned data from the start time to obtain corrected PET scanned data; and reconstructing the corrected PET scanned data within a second time (T2) to obtain a PET image. Scattering correction calculation is performed in advance by changing a calculation structure of PET scanning scattering correction, the time required for PET reconstruction after scanning is shortened, the clinical PET scanning imaging time is shortened, and the PET scanning efficiency is improved.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to a PET scanning data scattering correction method, device and computer equipment. Background technique [0002] With the axial lengthening of the PET system, the sensitivity of the system is also improved, which brings better image quality and shorter scanning time in clinical applications. But at the same time, as the number of crystals in the PET system increases, the number of Line-of-response (LOR) in the PET system increases with the square of the number of crystals, which greatly increases the amount of calculation required for PET reconstruction. [0003] In the traditional PET scanning process, the entire scanning process can be simplified into four parts: online scanning, preliminary data processing, scatter correction, and image reconstruction. The process can be further divided into two parts: online scanning process and offline processing process. Among the...
