Evaluation of optical 3D scanning system for radiotherapy use

INTRODUCTION: Optical three‐dimensional scanning devices can produce geometrically accurate, high‐resolution models of patients suitable for clinical use. This article describes the use of a metrology‐grade structured light scanner for the design and production of radiotherapy medical devices and synthetic water‐equivalent computer tomography images. METHODS: Following commissioning of the device by scanning objects of known properties, 173 scans were performed on 26 volunteers, with observations of subjects and operators collected. RESULTS: The fit of devices produced using these scans was assessed, and a workflow for the design of complex devices using a treatment planning system was identified. CONCLUSIONS: Recommendations are provided on the use of the device within a radiation oncology department.
