  • Stereographic X-ray examination system including graphic screen means for generating index marks to locate corresponding regions in different X-rays
    Patent number: 5245539
    Abstract: A light box for X-rays is made by using a graphics screen (20) coupled to a microprocessor (23), with the screen being used with inverse brightness. Under these conditions, the graphics screen emits light at nearly all points, other than special locations (I.sup.25) whose positions can be controlled by means of a control box (24). An X-ray negative (6) to be examined is placed over the graphics screen. The control box is used to move the non-illuminated regions of the screen to point to special locations in the negative. The light box is particularly applicable t studying stereographic negatives for mammography. It makes it possible to determine more quickly and more accurately the locations of lesions in breasts under examination.
