The apparatus includes a first plurality of detector elements, each detector element being configured to output signals indicative of an intensity of radiation that is incident thereon. The apparatus also includes a first plurality of adjustable collimator channels, each adjustable collimator channel being associated with and being positioned between a respective detector element and the body, each adjustable collimator channel having a second plurality of dimensional configurations defining respective different sets of the volume elements from which emitted radiation impinges on the respective detector element. A processor computes a radiation intensity from at least a portion of the volume elements in response to the signals output by the detector elements in at least two of the dimensional configurations of the adjustable collimator channels.

摘要： 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) within the body. The method includes providing single photon counting detector modules, 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, 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.
