Abstract
A radiation detection camera head having a focal-plane array of pixelated detectors having constant pitch between pixels over the whole of the camera head, while using detector modules having normal production tolerances, and which can nevertheless be readily removed and replaced in the detector array by means of predetermined gaps between adjacent detector modules. The pixels on the side walls of the detector modules have reduced size to maintain constant pitch over the array in spite of production variation between modules. The reduction in sensitivity due to this reduced size is compensated for by the addition of insulated conductive bands on the side walls. The head collimator is such that the septa fall between pixels and between modules, such that head sensitivity is maintained at its optimum value.
