Abstract
Disclosed is a system for forming a two-dimensional nuclear radiation image at a location inside an animal body and for transmitting a representation of the two-dimensional image to a location outside the body. In examining an animal body in accordance with the invention, a selected portion of the body is caused to form a nuclear radiation pattern, as by the ingestion or injection of a substance which gives out gamma radiation or by irradiation from an external source. The front end of an invented device is introduced into the body, as by way of a body cavity, to form a two-dimensional image of this nuclear radiation pattern. The middle part of the invented device transmits a representation of this two-dimensional image to the back end of the device, which is at a location outside the animal body which is being examined, where this representation forms an image of the selected animal body portion that can be viewed, recorded or otherwise utilized. The invented technique is used on a number of different devices, suitable for forming images under different conditions.
