Abstract
The disclosure concerns radiology instruments that include an X-ray source, a receiver of the film or film-screen type, a detection cell and means to compute the yield at the cell. The method consists of performing measurements of the yield at instants t.sub.1, t.sub.2, . . . t.sub.3 during the exposure, so as to determine the lumination or luminous exposure (the quantity of the light received multiplied by the exposure time) on the film and then computing the lumination remaining to be acquired to obtain the chosen optical density on the film.
