A CT imaging system includes a computer that is programmed to rebin cone beam projection data into a series of two-dimensional sinograms based on an optimized ray consistency approach. The computer receives cone beam data from a detector array and is programmed to specify a plurality of view angles for...http://www.google.com.hk/patents/US7933375?utm_source=gb-gplus-share專利 US7933375 - Ray consistency based reconstruction of helical cone beam data
