Accurate Proton Beam Localization

چکیده
The goal of this work was to further improve an experimental proton radiosurgery system at Loma Linda University Medical Center to reach sub-millimeter accuracy before proton radiosurgery with narrow beams can be used in a clinical trial. Radiosurgery precisely targets a specific anatomical region with high doses of radiation. We have developed a program that provides correcting translational offsets during target rotation and allows the proton beams to be aimed at the target from multiple directions in the proton research room. This was accomplished by developing and testing advanced image analysis software tools. The targeting accuracy was determined with a commercial stereotactic performance phantom. It was found that submillimeter targeting accuracy can be achieved with the

Embedded Crack Identification in Beam-Column Structures Under Axial Load Using an Efficient Static Data Based Indicator
A triangular model base on an investigation which has done by Sinha et al. has been developed for evaluating embedded crack localization in beam-column structures. In the assessment of this member’s behavior, the effects of displacement slope are necessary. In order to propose a crack localization method for embedded crack, an efficient static data based indicator is proposed for this crack in ...
متن کاملDose Assessment of Eye and Its Components in Proton Therapy by Monte Carlo Method
Introduction Proton therapy is used to treat malignant tumors such as melanoma inside the eye. Proton particles are adjusted according to various parameters such as tumor size and position and patient’s distance from the proton source. The purpose of this study was to assess absorbed doses in eyes and various tumors found in the area of sclera and choroid and the adjacent tissues in radiotherap...
متن کاملReview of Hadron Therapy Accelerators Worldwide and Future Trends
Hadron beams have attractive growing interest for cancer treatment owing to their high dose localization around the Bragg peak. Heavier-ions such carbon-ion beams, in particular, can realize higher 3D dose localization, compared with a proton beam, owing to a highly biological effect around the Bragg peak and a low multiple scattering effect. Recently, therefore, hadron cancer radiotherapy has ...
متن کاملImpact of Various Beam Parameters on Lateral Scattering in Proton and Carbon-ion Therapy
Background: In radiation therapy with ion beams, lateral distributions of absorbed dose in the tissue are important. Heavy ion therapy, such as carbon-ion therapy, is a novel technique of high-precision external radiotherapy which has advantages over proton therapy in terms of dose locality and biological effectiveness.Methods: In this study, we used Monte Carlo method-based Geant4 toolkit to s...
متن کاملPerformance characterization of a 3D liquid scintillation detector for discrete spot scanning proton beam systems.
Existing systems for proton beam dosimetry are limited in their ability to provide a complete, accurate, and detailed account of volumetric dose distribution. In this work, we describe the design and development of a portable, fast, and reusable liquid scintillator-based three-dimensional (3D) optical detection system for use in proton therapy. Our long-term goal is to use this system clinicall...
