Extracting brains from MR head images with PINCRAM

What it is

PINCRAM is a method for masking cranial MR images based on multiple atlases. It is loosely based on MAPER (Heckemann et al., Neuroimage 2010).

Software

Please download pincram here: pincram-0.2.7.tar.gz (5.5 KiB). Pincram requires GNU Bash version 3 or higher. Tested under Debian 8, Ubuntu 14.04, and RedHat Enterprise Linux Server release 6.7. Likely to work under Mac OS X. Dependencies: IRTK and Nifty Seg 0.9.4.

Atlas

You will also need a suitable source data set. For brain labelling we recommend ixi-pincram-atlas-n100-verified.tar (1.1 GiB). We are in the process of preparing a special atlas for labelling the intracranial volume.

Data sets used in the paper

Various atlas sets are used in the paper:

Hammers

The Hammers Atlas is a database of 30 MRI brain atlases of young healthy adults, available for download from www.brain-development.org (Resources - Atlases - Adult). The segmentations into 83 regions have been carefully prepared using a detailed, validated protocol which is described in the following two papers:

IXI

IXI is a database of 575 adult volunteers, available for download from www.brain-development.org (Resources - Datasets).

LPBA40

The LONI Probabilistic Brain Atlas (LPBA40) is a set of atlases prepared from 40 adult human volunteers.

OASIS

This is the atlas prepared for the MICCAI 2012 Grand Challenge and Workshop on Multi-Atlas Labeling from a subset of 30 adult volunteers selected from the Open Access Series of Imaging Studies (OASIS).
