BrainPET

HI

$/!\$ This page is only to process PET-MR data acquired using BrainPET (Bay 6) scanner at the Athinoula A. Martinos Center for Biomedical Imaging.

Aether-Mirror Version

This version mirrors the attenuation map generation and reconstruction algorithms that were used on Aether. We recommend to use this version only for continuation studies.

PseudoCT mu-map generation

This function generates pseudoCT mu-map using SPM8 atlas-based method (David Izquierdo-Garcia et al.)

For DICOM input:

perl brainPET_pCT_AeMir.pl -i /<DIR>/<SUJID>/MR/MPRAGE -f 107000-000005-000001.dcm -c 0

For NIFTI input

perl brainPET_pCT_AeMir.pl -i /<DIR>/<SUJID>/MR_PET -f cp_iso_mprage.nii -c 0

IMP1: The r-l flip is applied only to .dcm input but not to .nii input (see Imp2)
IMP2: If you input a nifti file, it should be named as cp_iso_mprage.nii and it should be r-l flipped (i.e., it is the output of a previously ran pesudo CT).

Supporting Functions

Denoise MPRAGE

perl brainPET_denoise_mprage.pl -i /<DIR>/<SUBJID>/MR_PET/cp_iso_mprage.nii -t 25 -s 0

ifile2nifti

perl brainPET_ifile2nifti.pl -i /<DIR>/file.i
