SYNOPSIS

mia-2dmyocard-icaseries -i <in-file> [options]

DESCRIPTION

mia-2dmyocard-icaseries 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.

OPTIONS

File-IO

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

input perfusion data set

-r --references=(output); string

File name base for the reference images. Image type and numbering scheme are taken from the input images.

-c --save-cropped=(output); string

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-feature=(output); 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.

Help & Info

-V --verbose=warning

verbosity of output, print messages of given level and higher priorities. Supported priorities starting at lowest level are:

info - Low level messages

trace - Function call trace

fail - Report test failures

warning - Warnings

error - Report errors

debug - Debug output

message - Normal messages

fatal - Report only fatal errors

ICA

-C --components=0

--normalize

normalized ICs

--no-meanstrip

don't strip the mean from the mixing curves

-s --segscale=1.4

-k --skip=0

-m --max-ica-iter=400

maximum number of iterations in ICAmaximum number of iterations in ICA

-E --segmethod=features

Segmentation method

delta-peak - difference of the peak enhancement images

features - feature images

delta-feature - difference of the feature images

Processing

--threads=-1

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).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).

EXAMPLE

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.
