NAME
mia-2dmyomilles - Run a registration of a series of 2D images.
SYNOPSIS
mia-2dmyomilles -i <in-file> -o <out-file> [options]
DESCRIPTION
mia-2dmyomilles This program is use to run a modified version of the ICA based registration approach
described in Milles et al. 'Fully Automated Motion Correction in First-Pass Myocardial Perfusion MR Image
Sequences', Trans. Med. Imaging., 27(11), 1611-1621, 2008. Changes include the extraction of the quasi-
periodic movement in free breathingly acquired data sets and the option to run affine or rigid
registration instead of the optimization of translations only.
