weasis

Weasis is a standalone and web-based software for visualizing images obtained from medical imaging devices. This free DICOM viewer is used in healthcare by hospitals, health networks, multicenter research trials, and patients.

General Features

• Flexible integration with PACS, VNA, RIS, HIS, or PHR (see integration documentation at https://nroduit.github.io/en/basics/customize/integration/)
• Web access through weasis protocol, see https://nroduit.github.io/en/getting-started/weasis-protocol
• Responsive user interface working well on high DPI screens, see https://nroduit.github.io/en/tutorials/theme/index.html#how-to-scale-the-user-interface
• Multi-language support at https://nroduit.github.io/en/getting-started/translating
• Configuration of preferences on server-side and client-side
• API for building custom plug-ins
• DICOM Send (storeSCU and STOW-RS)
• DICOM Query/Retrieve (C-GET, C-MOVE and WADO-URI) and DICOMWeb (QUERY and RETRIEVE)
• Dicomizer module to convert standard images into DICOM files
• Embedded DICOM viewer in CD/DVD or other portable media
