Abstract

Variable scan rate image generation is disclosed. A scanning device scans a scene with a detector array at a first constant scan rate. Photon accumulation values are iteratively transferred from each set of detector elements in the detector array to an adjacent set of detector elements at a first transfer rate based on the first constant scan rate. Photon accumulation values of one set of the plurality of sets are iteratively read out at the first transfer rate. The first constant scan rate is accelerated to a second constant scan rate, and photon accumulation values are iteratively transferred from each set to an adjacent set at a second transfer rate based on the second constant scan rate, and photon accumulation values of the at least one set of the plurality of sets are iteratively read out at the second transfer rate.
