Collision prediction software for radiotherapy treatments

Abstract: This methodology provides fast and reliable collision predictions using surface imaging. The use of the Kinect-Skanect system allows for a comprehensive modeling of the patient topography including all the relevant anatomy and immobilization devices that may lead to collisions. The use of this tool at the treatment simulation stage may allow therapists to evaluate the clearance of a patient's treatment position and optimize it before the planning CT scan is performed. This can allow for safer treatments for th… Show more

“…We successfully demonstrated a framework which can map an entire collision space a priori for a given patient during the time of simulation. While others have recently demonstrated collision avoidance using optical scanning systems, no one to our knowledge has demonstrated a system on actual patients. Furthermore, there has been a lack in clarity involving the registration of 3D scans to appropriate coordinates necessary to do accurate collision calculations.…”

“…Moreover, the framework presented did not create actual collisions, but nearby passes which provide less clarity on the accuracy of actual geometry collision avoidance. Neither of the most recent works in optical‐based collision avoidance relied on polygon interference for collision detection, even though both used polygon models for the phantom scans. The power of the polygon interference over simple cylindrical models is that it can quickly detect the overlap of complex geometries, which might be useful in future advanced trajectory treatments.…”
