Evaluation 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 کاملDosimetric Evaluation of Dose calculation algorithms of Monaco Treatment Planning System in the heterogeneities area
Introduction: In radiation therapy, the accuracy of dose calculations by a treatment planning system (TPS) is important to achieve tumor control and to spare normal tissue. Treatment planning system calculations in the heterogeneous situation may present significant inaccuracies. In this study, three different dose calculation algorithms, pencil beam (PB), collapsed cone (CC), ...
متن کاملCalculation of Thyroid Dose with Planner System and Evaluation of Thyroid Function after Radiotherapy for Patients with Breast Cancer
Background: Much research has widely been conducted into thyroid hormones levels following radiotherapy for breast cancer. Consequently, in this study, we evaluated to relate the rate of thyroid hormones levels with the dose distribution among breast cancer patients.Material and Methods: Thirty patients were treated with 4-field breast cancer radiotherapy. The dose volume histograms, the volume...
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 کاملPatient dose calculation software in nuclear medicine [Persian]
Introduction: Radioactive materials deliver internal radiation dose to patients in nuclear medicine. Manual internal radiation dose assessment is a complicated method. Introduction of a simple dose calculation software is the main goal of the present study. Methods: Using the best current data in internal dose calculation (S-Factors) recommended by ICRP and by cons...
