Title: Accelerating Image Reconstruction using Variable Splitting Method

Abstract:Statistical image reconstruction methods have been used in PET and SPECT commercially for well over a decade and have recently begun to appear commercially in X-ray CT systems, offering the possibility of reducing X-ray dose.  Iterative methods are also poised to impact clinical MRI. Computation time is a significant challenge for iterative image reconstruction methods, particularly in X-ray CT and MRI.  This talk will describe new developments in accelerating optimization methods for image reconstruction.
