Abstract

The purpose of this work is to study the feasibility of using PEImager scanner for positron emission mammography (PEM). PEM can be performed by using two opposite detectors. The two-detector positron projection imaging has less depth information, because of the limited number of line of responses (LORs). In this work, an iterative back projection algorithm is employed for reconstruction of projection data. Although the number of LORs are limited, the locations and sizes of hot spots in breast phantom still can be determined from the reconstructed images.
