Tackling the Challenge of Reirradiation: Intelligent Tools for Confidence Treating Complex Cases

As advancements in cancer care extend survival, retreatment cases are becoming routine—and managing prior dose, image registration, and radiobiological factors adds real complexity.

In this session, Radformation Clinical Success Manager Dan Frieling demonstrates a streamlined reirradiation workflow using AutoContour and ClearCheck. You'll see how these tools work together from accurate contouring and comprehensive registration to visualizing deformed dose and evaluating cumulative dose. The session also covered BED/EQD2 conversions and dose forgiveness to support informed, patient-specific decisions.

Highlights:

• Explored the growing need for retreatment tools, including deformable registration and BED/EQD2 support

• Discussed how AutoContour and ClearCheck simplify and strengthen the retreatment workflow


• Established key assumptions when applying BED/EQD2 and summing dose across treatment courses
