Apparatus for hybid scintigraphy

Abstract

The hybrid scintigraphy device allows scintigrams to be recorded of the whole body in one single scan made parallel to the body. A single rod shaped sodium iodide crystal is used. One of its longitudinal faces is plane and transparent and is in optical contact with a transparent protection plate. The other longitudinal faces are dulled and coated with a light scattering layer of MgO or Al/sub 2/O/sub 3/. On one side of the crystal a collimator is installed for the incident gamma or X-radiation, on the transparent side there are a number of photomultipliers. They are optically coupled with the surface of the crystal by means of an interconnected light conductor. The outputs of the photomultipliers are combined with each other in resistance networks, summers or subtracters and a delay network and electronic circuits for time measurement, respectively.
