WIPO Patent Application WO/2022/166976
Kind Code:
A1
Abstract:
A PET data correction method and apparatus, a computer device and a PET image reconstruction method. The PET data correction method comprises: acquiring a single event during a PET scanning process, wherein the single event comprises a non-scattering event and a scattering event (S101); acquiring a first correction parameter of the non-scattering event, and correcting the non-scattering event according to the first correction parameter (S102); acquiring a scattering feature of the scattering event, and classifying the scattering event on the basis of the scattering feature (S103); and acquiring a second correction parameter of a scattering event of a different type, and correcting the scattering events according to the second correction parameter (S104). By means of the PET data correction method, a reconstruction result is more accurate, and an imaging effect is better.
