[The uni-quatro camera - a new camera for documentation of monitor pictures (author's transl)].

A new camera system is described, which was devised to take pictures of monitor screens on special X-ray film, and it is compared with conventional methods of documentation. Quality of pictures obtained with this method is optimal, handling is quick and simple, and, in spite of that, the camera is smaller and less expensive than other multiformate cameras. Polaroid, special X-ray films and other films may be used interchangeable for all sorts of monitor screens. A report is given about the routine use of this system in ultrasonography.
