摘要

A process for producing and setting up a scattered radiation screen or collimator on an X-ray or gamma ray detector comprises forming a matrix of detector elements comprising sensitive regions (16a) and less sensitive intermediate regions (16b) on a structure with through channels and intermediate walls (6a) and an absorbing coating (14). Independent claims are also included for gamma and X-ray detectors for the above.
