Abstract
A detector module for use in scintillation cameras utilizes a plurality of elongated scintillator strips. A temperature gradient is established along the length of each strip. By identifying the particular strip in which a scintillation event has taken place and by measuring the decay time of the scintillation event, two-dimensional information can be developed. This permits a scintillation camera detector to be modularized and largely eliminates the problems of edge packing.
