Abstract

A radiation detection apparatus (100) acquires projection data of an object that is subject to motion during the acquisition. The apparatus includes a motion modeler (142) and a motion compensator (142) that cooperate to compensate for a motion of the object during the acquisition. In one example, the projection data includes list mode positron emission tomography data and the apparatus compensates for cardiac motion.
