This program is used to run a ICA on a series of myocardial perfusion images given in a segmentation set in order to create sythetic references that can be used for motion correction by image registration. If the aim is to run a full motion compensation then it is better run mia-2dmyoica-nonrigid, since this program is essentially the same without the registration bits.
input perfusion data set
File name base for the reference images. Image type and numbering scheme are taken from the input images.
save cropped set of the original set to this file, the image files will use the stem of the name as file name base
save the features images resulting from the ICA and some intermediate images used for the RV-LV segmentation with the given file name base to PNG files. Also save the coefficients of the initial best and the final IC mixing matrix.
verbosity of output, print messages of given level and higher priorities. Supported priorities starting at lowest level are:
|info:||Low level messages|
|fatal:||Report only fatal errors|
|trace:||Function call trace|
|fail:||Report test failures|

FastICA implementationto be used. For supported plug-ins see Plugin type: fastica/implementation
ICA components 0 = automatic estimation
don't strip the mean from the mixing curves
segment and scale the crop box around the LV (0=no segmentation)
skip images at the beginning of the series as they are of other modalities
maximum number of iterations in ICA
|delta-peak:||difference of the peak enhancement images|
|delta-feature:||difference of the feature images|
Maxiumum number of threads to use for processing,This number should be lower or equal to the number of logical processor cores in the machine. (-1: automatic estimation).
Evaluate the synthetic references from set segment.set and save them to refXXXX.??? by using five independend components, and skipping 2 images. Per default a bounding box around the LV will be segmented and scaled by 1.4 and the cropped images will be saved to cropXXXX.??? and a segmentation set cropped.set is created. The image file type ??? is deducted from the input images in segment.set.
