Abstract
A device for the high-speed analysis of photon- or particle-generated image data or for the high-speed energy-discrimination analysis of photon- or particle-counting data. The device uses a sensor that collects the photons or particles on an array of solid state detectors, as electrical analog signals, and stores the analog-signal information on capacitors of readout arrays associated with the detector arrays. Integration of the photon or particle flux signals on the readout arrays proceeds for a given time frame and then image-related signals are transferred to an analog correction processor. The analog correction processor is comprised of one or more integrated circuit chips where each chip contains an array of correction processor unit cells. In these unit cells signals are corrected, in parallel, for gain and offset nonuniformities in the detection and processing chain. Corrections to all the signals are made in a time frame or less and the information is then transferred to an analog image processor. Particle-counting data is transferred directly from the readout array chips to the analog image processor. The analog image processor is comprised of one or more integrated circui…
