ABSTRACT:
The patient's breast is pressed against an X-ray film vacuum cassette inserted into a holding arrangement mounted on the X-ray exposure-taking machine. With the patient in position, the technician can remove and insert cassettes from the side, without requiring the patient to move back away from the cassette holding arrangement as with prior-art holding arrangements. Two opposite ends of the loading platform of the holding arrangement are each provided with two holding brackets mounted slidable towards and away from the respective ends of the loading platform, but spring-biased towards the respective ends of the loading platform. The technician grips one end of the cassette, pushes its other end against the two holding brackets located remote from the side at which he is located, pressing those two holding brackets away from the holding platform until the end of the cassette held by him clears the two holding brackets proximate to him, whereupon he swings the cassette flat against the loading platform and relaxes his grip, the biasing springs pulling the two remote holding brackets towards the loading platform. The holding brackets extend along the narrow sides of the cassette and have inward ridges fitting over the edges of the cassette.
