摘 要:
We will present recent development in high accuracy methods for ECT medical image reconstruction. Several crucial issues including integral equation models, sparse regularization, and fast fixed point proximity algorithms in the development will be discuss ed. Numerical examples of both simulated data and clinical data will be presented to illustrate the proposed ideas.
