TIMESTAMPING DETECTED RADIATION QUANTA

摘要

The present invention relates to a radiation detection device, a system, a method and a computer program product for use in timestamping detected radiation quanta. The device comprises an optical detector pixel array, a timestamp trigger unit and a timing unit. The timestamp trigger unit determines a pixel cell triggering rate for pixel cells within the optical detector pixel array. The timestamp trigger unit causes the timing unit to generate a timestamp based on the pixel cell triggering rate.

1. A radiation detection device comprising:
an optical detector pixel array having one or more pixel cells which can be triggered by optical photons; a timestamp trigger unit in operative communication with at least one timing unit;wherein the timestamp trigger unit is configured to receive signals from the optical detector pixel array and is further configured to determine at least a first pixel cell triggering rate for the one or more pixel cells within the optical detector pixel array;wherein the at least a first pixel cell triggering rate is determined by computing the number of triggered pixel cells within the optical detector pixel array within a predetermined delay period;wherein the timestamp trigger unit is configured to cause the at least one timing unit to generate a first timestamp indicative of the end of the predetermined delay period based on the at least a first pixel cell triggering rate for the one or more pixel cells (9) within the optical detector pixel array.
