Abstract
A radionuclide camera was constructed that embodies a unique detector-collimator concept and provides a radically new approach to imaging. The heart of the instrument is a linear array of semiconductor detectors separated by thin tungsten plates that confine the field of view of each detector to 1 dimension. This collimator design has a higher collection efficiency than the standard parallel-hole collimator but cannot directly produce a 2-dimensional image. When multiple measurements are taken as the array rotates through 180.degree., a computerized image restoration algorithm can then produce 2-dimensional images with resolution determined by the width of the detectors. A small prototype camera has produced images with resolution superior to conventional Anger cameras.
