Description:

This program implements the motion compensation algorithm described in Wollny G, Kellman P, Santos A, Ledesma-Carbayo M-J, "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.

Options:

File-IO

-i, --in-file=(input, required); string

input perfusion data set

-o, --out-file=(output, required); string

output perfusion data set

-r, --registered=reg; stringSTRING

file name base for registered fiels

--save-cropped=STRING

save cropped set to this file

--save-feature=STRING

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.

--save-refs=STRING

save synthetic reference images

--save-regs=STRING

save intermediate registered images

Example:

Register the perfusion series given in 'segment.set' by using automatic ICA estimation. Skip two images at the beginning and otherwiese use the default parameters. Store the result in 'registered.set'.
