Three pillars of the platform

Case Library

Explore curated cases

Review structured reirradiation cases including clinical context, previous and current treatments, cumulative dose considerations, outcomes, and imaging.

Expert Network

Discuss challenging cases

Submit difficult clinical scenarios and receive structured recommendations from experienced reirradiation experts, including rationale and supporting evidence.

Advanced Review

Review imaging and treatment plans

Explore CT, MRI and PET imaging together with RTSTRUCT, RTDOSE, image registration, fusion, and selectable isodose overlays.

AI-assisted case entry

Upload clinical documents and review pre-filled structured fields.

Automatic RT organization

Planning CT, RTSTRUCT and RTDOSE organized from DICOM metadata.

Dose & isodose review

Review dose distributions and select relevant isodose levels in the viewer.

Role-based collaboration

Viewers, experts and administrators with dedicated permissions.

Why ReRAD?

Reirradiation decisions are complex, highly individualized, and often supported by limited evidence.
