Enhanced reconstruction for PET scanner with a narrow field of view by using backprojection method
2021 44th International Convention on Information, Communication and Electronic Technology (MIPRO)（2021）
摘要
There are several reconstruction methods for positron emission tomography (PET), but iterative methods based on maximum likelihood estimation are primarily used. In this paper, we propose a 2D reconstruction method for PET scanners that have a narrow field of view in the tangential direction and are based on the backprojection method. If a PET scanner has a reduced field of view in the tangential ...
