http://www.nitrc.org/forum/forum.php?forum_id=2436 We are pleased to announce the release of CMTK 2.1.1. Most significant addition in this release is a new tool, "epiunwarp", for correction of B0-field distortion in echo-planar MR images (e.g., diffusion-weighted images). The tool implements an algorithm by Holland et al. (NeuroImage 50(1):175-183, 2010) that requires two EPI acquisitions with opposing phase encoding direction, but no field map. This release also adds a simple tool ("gmm") for tissue classification using a Gaussian mixture model and atlas-based tissue priors. en-us Copyright 2000-2026 NITRC OSI Mon, 13 Apr 2026 8:06:00 GMT http://blogs.law.harvard.edu/tech/rss NITRC RSS generator
