摘要
A method and apparatus are provided for reconstructing images from data obtained from scintillation events occurring within a projection space of a depth-of-interaction positron emission tomography system (10). The method includes the steps of identifying a segment of each depth-of-interaction detector (16) of respective pairs of depth-of-interaction detectors detecting the scintillation events of the data obtained within the projection space and estimating a set of sinograms from the data based upon a set of depth-independent point spread functions (40) of the identified segments of the respective pairs of depth-of-interaction detectors.
