Proton arc therapy (PAT) is a novel modality to treat cancer, involving continuous rotation of the irradiation device around the patient while delivering a proton beam to the tumor. Compared to conventional fixed-angle proton beam delivery, PAT paves a promising treatment avenue, with numerous possible irradiation directions, to improve plan quality and streamline the treatment workflow. Nevertheless, this increased degree of freedom also becomes a burden for its clinical implementation, in particular in the treatment planning optimization step. The cornucopia of irradiation directions increases the complexity of the associated treatment planning optimization problem. It requires substantial computational power as well as the development of new algorithms and objectives to yield optimal treatment plans. This talk is dedicated to provide an overview of the PAT challenges and the proposed solutions to it.
