A radiology device includes an X-ray source for exposing a subject to the
radiation of said source, a converter for converting the X-rays into
optical images so as to form primary optical images, a transformer for
transforming the primary optical images into secondary optical images,
and a display for displaying the secondary images to a user. The
transformer includes an optical chain including, in succession, from the
output of the converter to the output of the device, an image enlargement
assembly exposed directly to the primary images from the converter, an
assembly for optical intensification of the enlarged images, and a
photosensitive matrix sensor for making the secondary images.
