About:
Weasis is a versatile, multi-platform DICOM viewer designed for medical imaging professionals and researchers. It provides robust tools for visualizing, annotating, and analyzing medical images directly from local files or PACS systems. Its key value lies in its open-source nature and extensive plugin support, enabling customized workflows for complex diagnostic tasks.
Key Features:
  • Cross-platform desktop application (Windows, macOS, Linux)
  • Supports DICOM from local files, CD/DVD, and PACS (DICOM Network)
  • Advanced visualization tools: 3D rendering, MPR, and image fusion
  • Extensible architecture with plugins for specialized modules
  • Measurement and annotation tools for clinical analysis
Use Cases:
  • Clinical review and diagnosis of CT, MRI, and X-ray scans
  • Medical imaging research and data analysis
  • Teaching and demonstration of radiological cases
Alternatives:
  • Horos – Horos is macOS-only, whereas Weasis offers true cross-platform support.
  • RadiAnt DICOM Viewer – RadiAnt is known for its speed and ease of use but is closed-source and lacks the extensibility of Weasis.
