Direct reconstruction of cardiac PET kinetic parametric images using a preconditioned conjugate gradient approach
Purpose: Our research goal is to develop an algorithm to reconstruct cardiac positron emission tomography (PET) kinetic parametric images directly from sinograms and compare its performance with the conventional indirect approach. Methods: Time activity curves of a NCAT phantom were computed accordi...
