Abstract
The radiography of a subject is improved by estimating the scattered radiation it transmits to the detectors. For this, one uses scattered radiation measured effectively through a simulacrum of the subject, with analogous attenuation properties, and which are modified by weighted coefficients obtained through a transformation of the values of total radiation received through the subject ( ) and the simulacrum ( ) selected. Thus it is also possible to improve radiographs without double irradiation of the subject to measure the scattered radiation separately.
