ITK-SNAP is a software application used to segment structures in 3D medical images. It is the product of a decade-long collaboration between Paul Yushkevich, Ph.D., of the Penn Image Computing and Science Laboratory (PICSL)
Compared to other, larger open-source image analysis tools, ITK-SNAP design focuses specifically on the problem of image segmentation, and extraneous or unrelated features are kept to a minimum. The design also emphasizes interaction and ease of use, with the bulk of the development effort dedicated to the user interface.
ITK-SNAP 3.2 is the first major release of ITK-SNAP in several years, and is funded by the NIH grant R01 EB014346. Version 3.2 includes an almost complete rewrite of the software, along with new features focused on multi-modality image support. Download the newest release of ITK-SNAP here!
