1. A method, comprising: generating, with a processor, a sonogram based on a plurality of photon coincidence events acquired via a detector ring assembly communicatively coupled to the processor; a step for selectively inserting, with the processor, one or more pseudo-slices into the generated sonogram while adjusting, with the processor, an axial position of one or more slices adjacent to the one or more pseudo-slices, wherein each of the one or more pseudo-slices comprises a blank, functional slice; and generating, with the processor, an image based on the updated sonogram including the one or more pseudo-slices.
