Interactive Volume Segmentation IVS is a medical image analysis tool written by Felipe Bergo and Alexandre Falcão at the Institute of Computing, Unicamp.

IVS is provided free of charge for use on Linux-based PCs (freeware, source code not included). IVS reads our own SCN 3D format, as well as 2D PGM images and medical images in Analyze format. DICOM images can be converted to SCN with the dicom2scn provided with IVS. IVS can perform several 3D preprocessing steps, such as interpolation, clipping, gradient computation and morphological operations. Semi-automatic volume segmentation is possible through the DIFT, as described in "Interactive Volume Segmentation with Differential Image Foresting Transforms", IEEE Transactions on Medical Imaging, 2003 (9) (1101-1109).

Current version, as of October 2005, is 2.6. The IVS quick guide was written for version 1.11. While the interface changed a bit, the operations required for segmentation are still the same.
