SYNOPSIS
mia2dmyoicafull i <infile> o <outfile> [options]DESCRIPTION
mia2dmyoicafull This program implements the 2D version of the motion compensation algorithm described in Wollny G, Kellman P, Santos A, LedesmaCarbayo MJ, "Automatic Motion Compensation of Free Breathing acquired Myocardial Perfusion Data by using Independent Component Analysis", Medical Image Analysis, 2012, DOI:10.1016/j.media.2012.02.004. The software may first run a linear registration and then a nonlinear registration or just one of the both.This version of the program may run all registrations in parallel.OPTIONS
