Method for estimating the radiation scattered in a two-dimensional detector

摘要

The radiation scattered in a two-dimensional detector (2) by a radiation is estimated by subjecting the detector (2) to at least two irradiations by inserting an array (3) of separated absorbers placed at variable distances (L) from the detector (2), measuring the (scattered) radiation at the shadow spots (6) of the absorbers and interpolating elsewhere to provide continuous images of the scattered radiation, and by deducing parameters modelling a scattered radiation distribution function in the detector.
