Weasis for Windows

Product snapshot

Weasis is a flexible, no-cost DICOM viewer built for both desktop environments and browser-based access. It helps clinicians and researchers open, inspect, and manage DICOM files — including both image series and associated reports — through an approachable graphical interface.

Main capabilities

• View DICOM-PR files and related presentation states for accurate image rendering
• Full DICOM-RT compatibility to support radiation therapy use cases
• Export imaging data and snapshots for reporting or secondary analysis
• Operate in a web-enabled mode to support remote review and cross-site workflows

Deployment and collaboration

Weasis runs locally and as part of web applications, making it possible to share cases and collaborate without forcing everyone onto the same physical machine. Its web support enables remote access, which is helpful for multi-site teams, telemedicine consultations, and decentralized research projects.

Who benefits most

This tool is suitable for radiologists, radiation oncologists, medical physicists, and imaging researchers who need a capable, cost-free viewer for daily image review, planning checks, or academic work. Its straightforward UI lowers the learning curve for new users while still offering functionality demanded by advanced users.

Alternative option

Suggested alternative: SHAREit (free) — a lightweight choice for users seeking a different approach to file sharing and viewing outside the typical clinical DICOM viewer ecosystem.
