An evolutionary optimization algorithm for proton arc therapy
Physics in Medicine & Biology, 2022Abstract Objective . Proton arc plan normally contains thousands of spot numbers and hundreds of energy layers. A recent study reported that the beam delivery time (BDT) is proportional to the spot numbers.

Treatment Planning in Arc Proton Therapy: Comparison of Several Optimization Problem Statements and Their Corresponding Solvers [PDF]
Computers in Biology and Medicine, 2022 Arc proton therapy (ArcPT) is an emerging modality in cancer treatments. It delivers the proton beams following a sequence of irradiation angles while the gantry is continuously rotating around the patient.

Phantom Assessment of Lung Dose From Proton Arc Therapy
International Journal of Radiation Oncology Biology Physics, 1997To compare resultant lung dose from proton arc therapy of the chest wall to that from electron arc therapy.A 200 MeV proton beam from the Indiana University Cyclotron was range shifted and modulated to provide a spread out Bragg peak extending from the surface to a depth of 4 cm in water.

Development of a standalone delivery sequence model for proton arc therapy
Medical Physics, 2023AbstractBackgroundSpot‐scanning proton arc (SPArc) has been drawing significant interests in recent years because of its capability of continuous proton irradiation during the gantry rotation. Previous studies demonstrated SPArc plans were delivered on a prototype of the DynamicARC solution, IBA ProteusONE.PurposeWe built a novel delivery sequence ...

A Multi-Arc and Constant-Energy-per-Arc Treatment Planning Method for Efficient Proton Arc Therapy
Medical PhysicsAbstract Background Proton arc therapy is an emerging proton modality with enhanced dose and linear energy transfer (LET) conformality to treatment targets. However, its delivery efficiency can be negatively impacted by frequent energy changes.
