Dose Calculation Accuracy and Algorithm Validation of Low Density Heterogeneities in Co
Telecobalt machine is one of the essential equipment needed in many cancer centers and still prominently used for the treatment of a variety of cancer cases in developing countries. This study aims to evaluate the impact of tissue heterogeneity corrections on 3D treatment planning system (Prowess). The human body contains a variety of tissues and cavities which vary widely in their physical and...
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 کاملthe comparative impact of prompts and recasts in processing instruction versus meaningful output-based instruction on efl learners’ writing accuracy
the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...
Study of Variation in Dose Calculation Accuracy Between kV Cone-Beam Computed Tomography and kV fan-Beam Computed Tomography
Cone-beam computed tomography (CBCT) images are presently used for geometric verification for daily patient positioning. In this work, we have compared the images of CBCT with the images of conventional fan beam CT (FBCT) in terms of image quality and Hounsfield units (HUs). We also compared the dose calculated using CBCT with that of FBCT. Homogenous RW3 plates and Catphan phantom were scanned...
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 ...
