VolViCon is an advanced application for three-dimensional visualization and image analysis of well-known modalities such as computed tomography (CT), magnetic resonance (MR), ultrasound, and x-rays images. It provides a wide variety of tools to analyze volume and surface data. It gives features for exporting 3D surfaces or volume as triangular mesh files for creating physical models using 3D printing technologies. It also provides high-quality visualization, linear and angular measurement tools, and various types of markups. It takes a single raw volume file or a sequence of 2D (i.e., DICOM) files and reconstructs 3D volume (voxels) and mesh (surfaces) models.

Import / Export Features

  • Supported file formats for import and export
  • Import and export current working environment as a project file (save your time and start working again where you left off)

  • Export support of well-known volume data as single file and DICOM slices as BMP, PNG, JPEG and TIFF (Convert DICOM to JPG or volume format)
  • Export support of DICOM slices as 3D mesh / surface model (Convert DICOM to mesh format i.e., STL, PLY, VRML, OBJ, IV)
  • Export slice stacks as a video file (i.e., MP4, AVI)
  • Export screenshots (including: BMP, JPG, PNG, TIF)
  • Import and export support for 3D landmarks/markups
  • Support for rendering multiple volumes/DICOM, and meshes
  • Mesh / surface reconstruction from volume/DICOM

Rendering / Tools

  • Support for creating various types of markups (landmarks/labels/fiducials) that are dynamically synchronized between all views
  • Support for saving all changes such as markups position, color, etc. for later use
  • Support for auto volume segmentation
  • Support for image analysis with various low-pass, high-pass and thresholding filters
  • Support for interactive surface editing
  • Interactive clipping planes support for volume visualization
  • Crop volume with an Interactive clipping box
  • Slice manipulation facilities (zoom, pan, rotation, brightness/contrast, etc.)
  • Distance and angle measurement tools.
  • Support of gradient presets with import and export feature
  • Volume transformation (reorientation and translation) and clipping tools
  • Interactive transformation to transform the mesh model with mouse interaction
  • Share surface/mesh models with Volume and Slice views to visualize transformation change simultaneously in all views
  • 3D mesh / surface cleaning, decimation, hole-filling, segmentation, aligning, comparing filters
  • High-quality (GPU) volume rendering projection
  • Pre-defined volume rendering presets
  • FDK cone beam reconstruction (transforms a set of 2D projection frames into a reconstructed 3D volume)

Extract Surface in 3 Clicks

reconstruction of 3D surfaces as triangular meshes for creating physical models using 3D printing technologies.

Step 1 - Import Volume or Images 

Import single volume data file or stack of (DICOM) Images

Step 2 - 3D Mesh / Surface Preview 

Go to “Surface Extraction” tab under “Volume” tab and click on “Preview”, the surface will be generated and a live preview of the extractable iso-surface will be renderered over the volume model.

Step 3 - Extract 3D Mesh / Surface

Adjust or specify the ISO value that controls the output of the extractable mesh / surface. Cropping or clipping using six clip planes can also be adjusted while previewing. Finally, press the “Extract” button.

Step 4 - Export as 3D Mesh File

Reconstructed mesh can be renderered as wireframe or points with flat or phong shading. The mesh can also be decimated or smoothed before exportation.


A new version of VolViCon has been released with lots of new features and improvement. (Changelog)

Loving the additions to the new version of Real3d VolViCon. It's a great, cleanly designed, user-friendly, volume data analysis and visualization program. So easy to use and robust. Please let us know if you want to add features of your requirement or businss collaboration.



"VolViCon is no doubt an elegant software for 3D image analysis and visualization. I couldn't find any other software that supports the visualization of multiple and large volume data, reconstructed surfaces, and landmark/markup in 3D. To save the current working environment as a project file has been an absolute lifesaver. I appreciate that the latest version has been released recently which feels fast, stable, and bugs free. Thank you!"
