Interaction characteristics from a plurality of pixels

摘要: One embodiment provides a method, including: receiving plurality of responses to an interaction occurring within photon detector pixel array, wherein the array comprises pixels; identifying subset pixels associated with interaction, each corresponds at least one responses; determining, from responses, characteristic of: time, position, and energy interaction; recording determined characteristic; collecting recorded interactions characteristics; selecting interactions, selection is based upon restricted range forming image selected interactions. Other aspects are described claimed.
