Abstract
Tomographic imaging of an inanimate object in which a fan-shaped beam of radiation is generated and divided into fan ray elements which are directed through a planar section of the object and detected by a set of detectors. Each detector produces a signal representative of the intensity of the radiation of a detected fan ray element and selected coordinates defining a cross-sectional image of the object are determined from the intensity signals of the detectors. The coordinates are stored and displayed on a display device. The detectors include a scintillation crystal which is provided with a half-solid cylinder of lead disposed on a side of the crystal.
