Prospects for Acceleration and Dose Reduction in Selected MR and X-ray CT Cardiovascular Applications
University of Wisconsin
There are likely to be significant advances in the acceleration of data acquisition in cardiovascular MR and X-ray CT in the near future. This presentation will emphasize an acquisition and reconstruction algorithm that has produced, with in vivo imaging and multiple simulations, acceleration factors between ten and several hundred for MR acquisitions that represent a motion free time series of images or images involving a series of variations in MR parameters. For the case of X-ray CT, simulations involving the decimation of in-vivo data suggest that dose in CT contrast-enhanced time series can be significantly reduced.
