A digital system of video signals of astronomical use was developed to be applied in the field of radiology. The images were obtained from radiologic films by means of a standard video camera.

The minimal specifications of the digital images for use in radiology are as follows:

a) 2.5 lpm spatial resolution, b) a digital resolution of 8 bits (256 gray levels). Images (194 by 154 mm in size) can be obtained. The software processing was adapted for treatment of the images in radiology.
