In Vivo Dosimetry of an Anthropomorphic Phantom Using the RADPOS for Proton Beam Therapy
The radiation positioning system (RADPOS) combines an electromagnetic positioning sensor with metal oxide semiconductor field-effect transistor (MOSFET) dosimetry, enabling simultaneous online measurement of dose and spatial position. Evaluation points can be determined with the RADPOS. The accuracy of in-vivo proton dosimetry was evaluated using the RADPOS and an anthropomorphic head and neck ...
متن کاملDesign of an Anthropomorphic Intensity Modulated Radiation Therapy Quality Assurance Phantom
The dynamic nature of IMRT delivery poses unique problems relating to the accurate and reproducible quality assurance of dose delivery. The usefulness of point detectors is limited to static fields and regions within low dose-gradients for treatment verification. However, dose distributions generated in intensity modulated radiation therapy (IMRT) often have complex shapes with high dose gradie...
متن کاملTowards Effective and Efficient Patient-Specific Quality Assurance for Spot Scanning Proton Therapy
An intensity-modulated proton therapy (IMPT) patient-specific quality assurance (PSQA) program based on measurement alone can be very time consuming due to the highly modulated dose distributions of IMPT fields. Incorporating independent dose calculation and treatment log file analysis could reduce the time required for measurements. In this article, we summarize our effort to develop an effici...
متن کاملEvaluation of Accuracy and Quality assurance of external beam therapy with photons
Introduction: Receiving exact dose by the patients is vital in radiotherapy. In radiation therapy, the dosimetry of radiations is too important because of successful radiation inquires for delivering the exact dose to the target volume. This study is to evaluate the tolerances and the accuracy of calculated dose of photon beams in the treatment software system. The TECDOC1583 p...
متن کاملDesign and implementation of an anthropomorphic quality assurance phantom for intensity-modulated radiation therapy for the Radiation Therapy Oncology Group.
PURPOSE To design, construct, and evaluate an anthropomorphic phantom for evaluation of intensity-modulated radiation therapy (IMRT) dose planning and delivery, for protocols developed by the Radiation Therapy Oncology Group (RTOG) and other cooperative groups. METHODS AND MATERIALS The phantom was constructed from a plastic head-shaped shell and water-equivalent plastics. Internal structures...
