Exploring beamline momentum acceptance of a medical gantry to deliver optimized tumour tracking plans
(2021)Background: Tumour tracking is particularly challenging to realise when it comes to proton therapy. The difficulty of assessing anatomical changes reliably enough to offset the treatment settings on-the-fly, while taking into account the finite range of particles, is beyond the current capabilities of beam delivery and image guidance technologies. Methods: To implement fast range corrections, momentum acceptance (±0.6% dp/p) and global ...Conference Poster -
ITV or tumour tracking for dose painting of NSCLC? A comparison of target coverage and out-of-target dose in proton treatments
(2021)Introduction: Dose-escalation radiotherapy is used to calculate biologically adapted plan. When treating moving tumours the boost on the dose can be lost. We investigated the possibility to use tumour tracking for high precision dose painting in lung cancers. We chose a case where the target motion was below 5mm, normally recruited under free-breathing/rescanning-only protocol. We performed a comparative 4D dose calculation (4DDC) analysis ...Conference Poster
