reconstructs and displays multiple image sets for accurate 3D targeting and trajectory planning. The software packages essential features for functional neurosurgery, tumor biopsy, and other procedures requiring precise stereotactic planning. NeuroSight Arc software simplifies preoperative trajectory planning for the CRW stereotactic system. The software, available on a laptop or workstation, is a module of the OmniSight EXcel platform and shares the same intuitive, straightforward interface. Visualization and analysis of images is fast and accurate, optimizing the selection of surgical approach.
