Abstract
Apparatus for examining a body by means of radiation such as X or .gamma. radiation includes a source of a substantially planar, sectoral-shaped swath of said radiation, collimator means having a plurality of apertures formed therein through which respective finger-like beams of the radiation can pass. The beams follow respective linear paths through a region of interest and toward detector means located on the opposite side of said region to the source; the detector means including a respective detector device for each of said finger-like beams. Conveniently each device consitutes a scintillator device and an associated photomultiplier tube, and the tubes associated with adjacent scintillator devices are misaligned to accommodate their widths. Means are also provided for orbiting the apparatus relative to said region of interest.
