发明名称 Method for determining the function representing the effect of non-reciprocity of a radiographic film
摘要 The invention relates to radiology systems and, more particularly in such systems, to a method that enables the effect of non-reciprocity of the radiographic film to be determined. This effect of non-reciprocity is expressed by coefficients CNRD(di) which are a function of the photon dose rate (di) on the film, the coefficients CNRD(di) being obtained from the coefficients CNRT(ti) and the determination of the reference lumination Lref received by the film.
