Dose calculation accuracy of lung planning with a commercial IMRT treatment planning system
The dose calculation accuracy of a commercial pencil beam IMRT planning system is evaluated by comparison with Monte Carlo calculations and measurements in an anthropomorphic phantom. The target volume is in the right lung and mediastinum and thus significant tissue inhomogeneities are present. The Monte Carlo code is an adaptation of the MCNP code and the measurements were made with TLD and fi...
متن کاملDose calculations accuracy of TiGRT treatment planning system for small IMRT beamlets in heterogeneous lung phantom
Background: Accurate dose calculations in small beamlets and lung material have been a great challenge for most of treatment planning systems (TPS). In the current study, the dose calculation accuracy of TiGRT TPS was evaluated for small beamlets in water and lung phantom by comparison to Monte Carlo (MC) calculations. Materials and Methods: The head of Siemens Oncor-impression linac...
متن کاملAssessment of Dose Calculation Accuracy of TiGRT Treatment Planning System for Physical Wedged fields in Radiotherapy
Introduction Wedge modifiers are commonly applied in external beam radiotherapy to change the dose distribution corresponding to the body contour and to obtain a uniform dose distribution within the target volume. Since the radiation dose delivered to the target must be within ±5% of the prescribed dose, accurate dose calculation by a treatment planning system (TPS) is important. The objective ...
متن کاملEvaluation of Dose Calculation Accuracy of Isogray Treatment Planning System in Craniospinal Radiotherapy
Introduction: Craniospinal radiotherapy is a therapeutic technique for central nervous system (CNS) tumors, which requires meticulous attention to technique and dosimetry.Treatment planning system (TPS) is one of the main equipment in radiotherapy; therefore, the evaluation of its accuracy is essential for dose calculation. The present study evaluates the validity of Isogray TPS in craniospinal...
متن کاملAssessment of out-of-field dose calculation algorithm by commercial treatment planning systems in IMRT and 3DCRT
Abstract Introduction: The accuracy an assessment of out- of- field dose due to secondary cancer risk is clinically important. Actually radiotherapy treatment planning systems are not commissioned for the out-of-field dose calculations, so the estimation of dose distributions by TPSs beyond the borders of treatment fields is not well calculate...
