Patent number: 12159330Abstract: Upon receiving list-mode data by detecting radiation emitted from a radiation source positioned with a field of view of a medical imaging scanner, each photon included in the list-mode data can be classified according to one or more interaction properties, such as energy or number of crystals interacted with. Grouped pairs of photons can be generated based on the classifying, and a corresponding interaction-property-specific correction kernel (e.g., a corresponding interaction-property-specific point spread function correction kernel) can be selected for each group. Corresponding interaction-property-specific correction kernels can then be utilized to generate higher quality images.Type: GrantFiled: February 17, 2022Date of Patent: December 3, 2024Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Wenyuan Qi, Qiang Yi, Evren Asma, Li Yang, Peng Peng
