Questions
- Do these tools upload patient data?
- The browser tools parse and keep data locally in your browser — nothing you paste is sent to a server. Prefer synthetic messages and studies. Dicommunication runs on your trusted network (Docker, MSI, or DMG) and talks DICOM to nodes you configure. DICOM Camera is a lab/pilot Android app, not authorised for clinical use.
- Are the tools free to use?
- Yes. The web tools run in the browser at no charge. Dicommunication is a GitHub project with Docker, MSI, and DMG builds. DICOM Camera is published as a lab/pilot build on GitHub, not as a CE-marked clinical product.
