Abstract
Abstract A light weight gamma camera head and assemblies and kits which embody it. The gamma camera head has a detector assembly which includes an array of room temperature, solid state spectroscopy grade detectors each associated with a collimator and preamplifier, which detectors and associated collimators and preamplifiers are arranged in parallel rows extending in a first direction and suitably spaced from each other in a second direction normal to said first direction, each of the parallel detector rows holding a plurality of detectors. The head further has electric motor means for moving the detector means in the second direction and optionally also in the first direction, either stepwise or continuously.
