NAME

mia-3dbrainextractT1 - Extract the brain from a 3D T1 MRI head image.

SYNOPSIS

mia-3dbrainextractT1 -i <in-file> -o <out-file> [options]

DESCRIPTION

mia-3dbrainextractT1 This program is used to extract the brain from T1 MR images. It first runs a combined fuzzy c-means clustering and B-field correction to facilitate a 3D segmentation of 3D image. Then various fiters are run to obtain a white matter segmentation as initial mask that is then used to run a region growing to obtain a mask of the whole brain. Finally, this mask is used to extact the brain from the B0 field corrected images.

OPTIONS

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

input image(s) to be segmented
For supported file types see PLUGINS:3dimage/io

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

brain mask
For supported file types see PLUGINS:3dimage/io

-n --no-of-classes=3

number of classes

-w --wm-class=2

index of white matter

-p --wm-prob=0.7

white matter class probability for initial mask creation

-t --grow-threshold=20

intensity threshold for region growing

--grow-shape=18n

neighbourhood mask region growing
