Import structures and start planning process

I can't believe how easy the integration was. Radformation makes the workflow amazing for REAL users like us. Plus, the contours from AutoContour are superior to anything I've seen.

AutoContour reduced required dosimetrist time by up to 1.5 hours/case for complex cases.

    AutoContour Overview

    By automatically contouring OARs and planning structures in seconds, AutoContour drastically reduces the amount of time it takes to create contours for a patient and improves contouring consistency across clinicians.
