Abstract: The invention concerns a method for coating a support (10) comprising a first material with a coating layer comprising a second material, including at least a phase (A, A?) for deposition of a layer of given thickness of coherent material (11, 13) on the support surface during which the interaction between an ion source and a plasma is used. The invention is characterized in that each phase (A, A?) of material deposition is followed by a phase (B, B?) for exposure of the support and the deposited layer of material (11, 13) to a pulse of limited duration of an ionic bombardment with high energy density of selected energy density level.
Abstract: A radiology device comprising an X-ray source (11) for exposing a subject (S) to the radiation of said source, means (12) for converting the X-rays into optical images so as to form primary optical images, means (20) for transforming the primary optical images into secondary optical images, and means (40) for displaying the secondary images to a user, characterized in that the means for forming the secondary optical images comprise an optical chain comprising in succession, from the output of the converter to the output of the device, an image enlargement assembly (22) exposed directly to the primary images from said conversion means (12), an assembly (23) for optical intensification of the enlarged images and a photosensitive matrix sensor (25) for making said secondary images.
