Beam commissioning of a new compact scanned proton therapy system with four different dose calculation algorithms.

ABSTRACT:

Background

The Central Japan International Medical Center (Gifu prefecture, Japan) as the 20th Proton Therapy Institution in Japan, has newly installed a compact scanned proton therapy system, ProBeam 360°™. We installed two commercial treatment planning systems (TPSs): Eclipse and RayStation. No commissioning results have been reported between Varian's newest compact proton therapy system and the two TPSs.​ PURPOSE: We identified the optimal dose calculation algorithm for clinical use by evaluating the dose agreements between four dose calculation algorithms provided by two TPSs and the measured values using our new machine.

Methods

The two TPSs each had a pencil beam algorithm (PBA) and Monte Carlo (MC) dose engines (four in total). Validation plans were created for 26 box
