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.

-n --no-of-classes=3
number of classesnumber of classes

-w --wm-class=2
index of white matterindex of white matter

-p --wm-prob=0.7
white matter class probability for initial mask creationwhite matter class

EXAMPLE

Create a mask from the input image by running a 5-class segmentation over inpt image
input.v and use class 4 as white matter class and store the masked image in masked.v and
the B0-field corrected image in b0.v

mia-3dbrainextractT1 -i input.v -n 5 -w 4 -o masked.v
