Label training data

The professional software for medical image segmentation.

From medical image to precise 3D model. For research, manufacturing, and AI training.

Medical volume data contains far more information than a simple viewer can reveal. The Dornheim Segmenter gives you the tools to extract this information: delineate structures with precision, generate print-ready 3D models, analyze volumes and geometries, and label training data for AI algorithms – all in a single desktop application, locally and with no cloud lock-in.

Everything you need for segmentation

From the first mask to the print-ready model: a complete toolset for research, 3D printing, and AI development.

Intelligent segmentation

Binary masks and complex structures – created in no time thanks to semi-automatic tools.

  • Slice-by-slice segmentation with shape interpolation
  • Thresholding, region growing, ROI selection
  • Interactive 3D cutting and sculpting
  • Intelligent separation of connected structures
Print-ready 3D models

Watertight mesh models straight from your data – for 3D printing, VR, and simulation.

  • Sub-voxel-optimized model generation
  • Smoothing and repair of mesh defects
  • Export to STL, OBJ, VRML, STEP, IGES
  • Simplification and refinement of meshes
AI training & labeling

Annotate data sets efficiently and create ground-truth data for AI systems.

  • Efficient labeling of 3D data sets
  • Creation of ground-truth data
  • Validation of AI algorithms
  • Export of structured training data
Geometric analysis

Volumes, surfaces, distances, and angles – calculated automatically from your segmentations.

  • Automatic volume and surface calculation
  • Length, angle, and area measurements
  • Cross-section and distance analyses
  • Ideal for clinical studies and research
Flexible formats

Import and export in all relevant formats – from DICOM to CAD, from voxel to mesh.

  • Import: DICOM, RAW, VGI, image stacks, 3D models
  • Voxel ↔ mesh conversion in both directions
  • Export for CAD, simulation, and animation
  • Support for Dornheim Real Anatomy (.SEG)
DICOM Viewer included

The full feature set of the Dornheim DICOM Viewer is already included.

  • Volume rendering of segmented structures
  • DICOM conversion and anonymization
  • Import of DICOM, image stacks, and raw data
  • Local data storage – no forced upload
