Open source software for reconstruction of computed tomography and magnetic ressonance images. Available for the Microsoft Windows, GNU/Linux and Apple Mac OS X platforms. –


InVesalius generates 3D medical imaging reconstructions based on a sequence of 2D DICOM files acquired with CT or MRI equipments. InVesalius is internationalized (currently available in English, Portuguese, French, German, Spanish, Catalan, Romanian, Korean, Italian and Czech), multi-platform (GNU Linux, Windows and MacOS) and provides several tools:

  • DICOM-support including: (a) ACR-NEMA version 1 and 2; (b) DICOM version 3.0 (including various encodings of JPEG -lossless and lossy-, RLE)
  • Support to Analyze files
  • Support to BMP, PNG, JPEG and TIF files
  • Image manipulation facilities (zoom, pan, rotation, brightness/contrast, etc)
  • Segmentation based on 2D slices
  • Pre-defined threshold ranges according to tissue of interest
  • Segmentation based on watershed
  • Edition tools (similar to Paint Brush) based on 2D slices
  • Linear and angular measurement tool
  • Volume reorientation tool
  • 3D surface creation
  • 3D surface volume measurement
  • 3D surface connectivity tools
  • 3D surface exportation (including: binary and ASCII STL, PLY, OBJ, VRML, Inventor)
  • High-quality volume rendering projection
  • Pre-defined volume rendering presets
  • Volume rendering crop plane
  • Picture exportation (including: BMP, TIFF, JPG, PostScript, POV-Ray)
