20110176745 | METHOD AND SYSTEM FOR REDUCING ARTIFACT DUE TO TIME DELAY IN DATA ACQUISTION SYSTEM IN COMPUTER TOMOGRAPHY - The CT imaging system optimizes its image generation by substantially reducing artifacts caused by a known amount of readout time lag in the X-ray detectors or data acquisition system. Although each detector row takes the same amount of time to read out the signals, the time lag cumulates over the rows as each row is sequentially read out. The back-projection coordinates are correspondingly corrected based upon the above described delay. | 07-21-2011 |
