Dynamic Delivery Planning in Iba Proton Pencil Beam
نویسنده
چکیده
Pencil Beam Scanning is a dynamic beam delivery system developed for proton therapy. The radiation field necessary to reach in a fast and robust way a prescribed 3D dose distribution is obtained by accurately controlling both the extraction of the beam from a 235 MeV accelerator and the motion of the beam spot thanks to scanning magnets. This paper focuses on the trajectory planning aspect of this control problem, i.e. the calculation of the desired time evolution of the beam current and scanning magnets voltages to reach a desired profile in minimum time while satisfying the actuator constraints.

متن کاملIba Proton Pencil Beam Scanning: an Innovative Solution for Cancer Treatment
Particles are used in medical application for cancer treatment. Radiotherapy aims to deliver a high dose in a well-defined target volume while sparing the healthy surrounding tissues. Compared to the conventional radiotherapy (X-ray), protons show superior clinical performances thanks to their inherent depth dose characteristic (Bragg peak). In proton therapy, several techniques can be used to ...

This work proposes a generic method for modeling scanned ion beam delivery systems, without simulation of the treatment nozzle and based exclusively on beam data library (BDL) measurements required for treatment planning systems (TPS). To this aim, new tools dedicated to treatment plan simulation were implemented in the Gate Monte Carlo platform. The method was applied to a dedicated nozzle fro...

متن کاملGolden beam data for proton pencil-beam scanning.
Proton, as well as other ion, beams applied by electro-magnetic deflection in pencil-beam scanning (PBS) are minimally perturbed and thus can be quantified a priori by their fundamental interactions in a medium. This a priori quantification permits an optimal reduction of characterizing measurements on a particular PBS delivery system. The combination of a priori quantification and measurements...
