The EnSite Verismo Segmentation Tool is an easy-to-use, highly user friendly software, designed to provide a precise 3 Dimensional (3D) view of the cardiovascular structure. The Segmentation Tool converts standard CR or MR images into a 3D model, to improve pre-planning and creation of geometry. It uses a simple point-and-click interface to operate, and should be installed on an EnSite System workstation, as this will ensure greater control over the post-process images. The system is compatible with DICOM3 data set for any CT or MR scanner and allows users to simultaneously view 3D models and created geometries, in order to analyse conditions better.
