InVesalius is a free, open-source medical imaging application designed for three-dimensional reconstruction from computed tomography and magnetic resonance imaging scans. It converts sequences of two-dimensional DICOM images into detailed anatomical models. The software supports medical image visualization, segmentation, and measurement through an interactive graphical environment. Users can isolate tissues using threshold ranges, watershed segmentation, and manual editing tools. It provides high-quality volume rendering and three-dimensional surface generation for examining anatomical structures. Reconstructed models can be exported in formats such as STL, OBJ, and PLY for further processing or 3D printing. Available for Windows, macOS, and Linux, InVesalius supports medical research, education, and anatomical visualization workflows.
