Golden 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...
متن کاملPencil Beam Scanning Proton Therapy for Rhabdomyosarcoma of the Biliary Tract
Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma of childhood with 250-350 cases diagnosed annually in the United States. Biliary tract rhabdomyosarcoma is rare, representing <1% of the RMS cases. Due to its location, resection is clinically challenging, and functional complications exist and persist from biliary obstruction. The anatomical location of this tumor presents both oppo...
متن کاملA comparison of two pencil beam scanning treatment planning systems for proton therapy
OBJECTIVE Analytical dose calculation algorithms for Eclipse and Raystation treatment planning systems (TPS), as well as a Raystation Monte Carlo model are compared to corresponding measured point doses. METHOD The TPS were modeled with the same beam data acquired during commissioning. Thirty-five typical plans were made with each planning system, 31 without range shifter and four with a 5 cm...
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 ...
متن کاملCommissioning of the world's first compact pencil‐beam scanning proton therapy system
This paper summarizes clinical commissioning of the world's first commercial, clinically utilized installation of a compact, image-guided, pencil-beam scanning, intensity-modulated proton therapy system, the IBA Proteus® ONE, at the Willis-Knighton Cancer Center (WKCC) in Shreveport, LA. The Proteus® ONE is a single-room, compact-gantry system employing a cyclotron-generated proton beam with im...
