This presentation is concerned with television camera tubes that respond directly to incident penetrating radiation. In its simplest form, the camera tube consists of a layer which converts the incident penetrating radiation field into a charge pattern which is scanned by an electron beam to form an image that is displayed using conventional closed-circuit television (CCTV) techniques. Such a tube has a number of advantages, the principal one of which is its simplicity. With this simplicity, however, in terms of the number of elements involved, come a number of problems which to date have essentially kept such an approach to X-ray imaging from commercial application. It is the purpose of this presentation to detail the advantages, disadvantages, and difficulties in the implementation of the X-ray-sensitive television camera tube.
