Abstract

Positron range effect is one of the fundamental factors limiting the spatial resolution of PET images. In statistical image reconstruction methods, positron range effects can be incorporated into the system model. The resolution recovery by modeling positron range results in an inevitable increase of image noise. We compare the resolution and noise properties of the images reconstructed with or without positron range modeling in this paper. Simulation results show that positron range modeling can lead to improved resolution vs. noise trade-off.
