NAME
mia-2dmyoica-nonrigid2 - Run a registration of a series of 2D images.
SYNOPSIS
mia-2dmyoica-nonrigid2 -i <in-file> -o <out-file> [options]
DESCRIPTION
mia-2dmyoica-nonrigid2 This program runs the non-rigid registration of an perfusion image series.In each pass, first an ICA analysis is run to estimate and eliminate the periodic movement and create reference images with intensities similar to the corresponding original image. Then non-rigid registration is run using the an "ssd + divcurl" cost model. The B-spline c-rate and the divcurl cost weight are changed in each pass according to given parameters.In the first pass a bounding box around the LV myocardium may be extractedto speed up computation Special note to this implemnentation: the registration is always run from the original images to avoid the accumulation of interpolation errors.
