Abstract: A scintillation camera to image subjects using high energy photons (HEP's), having a HEP collimator for passing only some of the HEP's received from the subject, a HEP detector made of a scintillating material which produces visible light photons (VLP's) when it absorbs HEP's, a VLP collimator for passing only some of the VLP's received from the HEP detector, a VLP detector employing photomultiplier tubes (PMT's) having an array of anodes disposed within anode regions that are wired such that only some of the anodes in a given column are wired to the column lead, and only some of the anodes in a given row are wired to a row lead, with the row leads and column leads of the different anode regions being individually addressable, and also employing processing circuitry to receive the electrical signals from the VLP detector and convert them to electronic representations of the subject, which are then converted into an image by a display.
