NAME

('mia\-2dmyocard\-ica',) - Run an ICA analysis on a series of 2D images

SYNOPSIS

mia-2dmyocard-ica -i <in-base> [options]

DESCRIPTION

mia-2dmyocard-ica This program is used to run a ICA on a series of myocardial perfusion images 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 to create a segmentation set and use mia-2dmyoica-nonrigid. If the input data is given by means of a segmentation set, then on can also use mia-2dmyocard-icaseries. This program is essentially used to test different options on how to run the ICA forreference image creation.

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).

PLUGINS: 2dimage/io

bmp
BMP 2D-image input/output support. The plug-in supports reading and writing of binary images and 8-bit gray scale images. read-only support is provided for 4-bit gray scale images. The color table is ignored and the pixel values are taken as literal gray scale values.

('Recognized file extensions: ', '.BMP, .bmp')

Supported element types:
binary data, unsigned 8 bit

datapool
Virtual IO to and from the internal data pool

('Recognized file extensions: ', '.@')

dicom
2D image io for DICOM

('Recognized file extensions: ', '.DCM, .dcm')

Supported element types:
signed 16 bit, unsigned 16 bit

exr
a 2dimage io plugin for OpenEXR images

('Recognized file extensions: ', '.EXR, .exr')

Supported element types:
unsigned 32 bit, floating point 32 bit

jpg
a 2dimage io plugin for jpeg gray scale images

('Recognized file extensions: ', '.JPEG, .JPG, .jpeg, .jpg')

Supported element types:
unsigned 8 bit

png
a 2dimage io plugin for png images

('Recognized file extensions: ', '.PNG, .png')

Supported element types:
binary data, unsigned 8 bit, unsigned 16 bit

raw
RAW 2D-image output support

('Recognized file extensions: ', '.RAW, .raw')

Supported element types:
binary data, signed 8 bit, unsigned 8 bit, signed 16 bit, unsigned 16 bit, signed 32 bit, unsigned 32 bit, floating point 32 bit, floating point 64 bit

tif
TIFF 2D-image input/output support

('Recognized file extensions: ', '.TIF, .TIFF, .tif, .tiff')

Supported element types:
binary data, unsigned 8 bit, unsigned 16 bit, unsigned 32 bit

vista
a 2dimage io plugin for vista images

('Recognized file extensions: ', '.-, .V, .VISTA, .v, .vista')

Supported element types:
binary data, signed 8 bit, unsigned 8 bit, signed 16 bit, unsigned 16 bit, signed 32 bit, unsigned 32 bit, floating point 32 bit, floating point 64 bit

PLUGINS: fastica/implementation

internal
This is the MIA implementation of the FastICA algorithm.

(no parameters)
itpp
This is the IT++ implementation of the FastICA algorithm.

(no parameters)

EXAMPLE

Evaluate the synthetic references from images imageXXXX.exr and save them to refXXXX.exr by using five independend components, mean stripping, normalizing, and skipping 2 images.

mia-2dmyocard-ica -i imageXXXX.exr -o ref -k 2 -C 5 -m -n
