A positron imaging apparatus (102) acquires projection data indicative of positron annihilations in an object under examination. A local reconstructor (146) performs an iterative local reconstruction of truncated projection data to produce image space data indicative of the object. A motion compensator (142) compensates for a motion of the object; an image combiner (148) combines the image space data with other image space data indicative of the object.
