Method for estimation of scattered radiation, in particular for the correction of x-ray images

摘要

The radiography of an object is improved by estimating the diffused radiation that it transmits to the detectors. For this purpose, it is of the radiation diffused actually measured through a travesty of the object, having the properties of the attenuation the like, and which is modified by the weighting coefficients obtained by a transformation of the values of the total radiation received through the object (3) and the selected travesty (8). It is thus possible to improve the radiographies not be subjected to a double irradiation to the object to measure separately the radiation scattered.
