normalize_pet

intensity normalize a PET MINC volume

normalize_pet [options] <norm.mnc> [<in.mnc>] <out.mnc>

DESCRIPTION

normalize_pet performs intensity normalization on a PET (Positron Emission Tomography) MINC volume. The program scales the intensity values so that the mean value within a specified mask region equals the target normalized mean.

If both in.mnc and out.mnc are specified, the normalization factor is computed from norm.mnc and applied to in.mnc, writing the result to out.mnc. If only out.mnc is specified, the normalization is computed from and applied to norm.mnc.

OPTIONS

-mask maskfile
Specify a mask file to restrict normalization to a region of interest. Only voxels within the mask are used to compute the normalization factor.
-normalized_mean value
Target mean value for the normalized volume. Default: 100.

EXAMPLES

Normalize a PET volume to a mean of 100:

normalize_pet pet.mnc normalized.mnc

Normalize using a mask and apply to a different volume:

normalize_pet -mask brain_mask.mnc -normalized_mean 50 norm.mnc input.mnc output.mnc
