Abstract: A method for imaging a body, including scanning the body so as to generate a tomographic image thereof, and analyzing the tomographic image to determine a location of a region of interest (ROI) (38) within the body. The method includes providing single photon counting detector modules (40), each of the modules being configured to receive photons from a respective direction and to generate a signal in response thereto. The method further includes coupling each of the modules to a respective adjustable mount (54), adjusting each of the adjustable mounts so that the direction of the module coupled thereto is aligned with respect to the location so as to receive radiation from the ROI, operating each of the modules to receive the photons from the ROI, and, in response to the signal generated by each of the modules, generating a single photon counting image of the ROI.

Abstract: A pixelated detector for detecting photons is provided comprising: a semiconductor crystal; a cathode electrode on a first surface of the crystal; an anode comprising a plurality of anode pixel electrodes on a second surface of the crystal; and a signal generator that receives signals from at least one electrode of the electrodes. When a photon is incident on the detector the signal generator generates a timing signal responsive to signals induced on the at least one electrode by electrons and holes produced by the incident photon and the at least one electrode has a size larger than the size of a single anode pixel electrode.
