Time-of-Flight camera for patient motion monitoring in medical applications

Résumé

Time-of-Flight (ToF) cameras are a promising new technology for medical imaging. This study aims at determining the achievable motion estimation accuracy and its associated repeatability of ToF camera for patient motion management in medical applications. Measurements were carried out using an anthropomorphic phantom associated with a linear actuator to produce a range of movements. Different camera angles were also considered. Our results show a reliable accuracy and robust repeatability (±1mm) thanks to a B-Splines surface modeling as opposed to the use of the camera raw data. ToF camera could therefore be used in radiotherapy for respiratory gating and inter-fraction patient positioning.
