Abstract
A radionuclide emission tomography camera for sensing gamma ray emissions from a source within the field of view, including: a fixed position-sensitive detector, responsive to the gamma ray emissions and surrounding the field of view, for detecting the contact position and the trajectory from which a gamma ray emission originates; a rotatable collimator disposed between the fixed position-sensitive detector and the field of view and including at least one array of collimator elements for restricting and collimating the gamma ray emissions; and means for rotating the collimator relative to the fixed position-sensitive detector for exposing different sections of the position-sensitive detector to the gamma ray emissions in order to view the source from different angles.
