WorkingCompany's own claimOfficial ↗

Problem

Radiotherapy planning required doctors to mark organs on CT images so treatment could spare healthy tissue. Manual contouring took time and varied between clinicians.

Approach

UZ Leuven clinicians and medical physicists worked with KU Leuven engineers to build a deep-learning tool. They tested it in the laboratory before introducing it into clinical practice. Doctors reviewed and corrected the generated contours, and the hospital reported daily use.

Results

about 33%faster contouring with the algorithm and physician correction than manual contouring, according to UZ LeuvenCompany's own claim[1]

Takeaway

The reported speed improvement included physician review and corrections. Human checking remained part of the clinical workflow.
