title: Simple and efficient system for fast interchange of low-energy collimators.
abstract: The inconvenience and time required for changing collimators on a scinticamera are major problems in the efficient use of the apparatus. A system is described, based on the lightweight, reversible DIVCON collimator made by Searle Radiographics for the Pho/Gamma camera that solves this problem. The core of a straight-bore, low-energy collimator is adapted to fit the DIVCON outer ring and a low-energy pinhole collimator is constructed to fit the same mounting system. Finally, an adapter using a bayonet-mount slot system is added to make collimator changing by hand possible in a minute or less.
