Dosimetric Study of Tissue Heterogeneity Correction for Breast Conformal Radiotherapy
Introduction: Heterogeneity correction is an important parameter in dose calculation for cancer patients where it may be cause inaccuracy in dose calculation as a result of different densities of patients. This study studied the impact of dose calculation of breast cancer patients with and without heterogeneity correction. Material and Methods: Twenty breast cancer patients were treated with Th...
متن کاملDetermination of Dosimetric Characteristics of IrSeed 125I Brachytherapy Source
Introduction Low dose rate brachytherapy sources have been widely used for interstitial implants in tumor sites, particularly in prostate. Dosimetric characteristics of a new IrSeed 125I brachytherapy source have been determined using the LiF thermoluminescent dosimeter (TLD) chips. Materials and Methods Dose rate constant, radial dose function, and anisotropy function around the IrSeed 125I so...
متن کاملModification of Source Strength in Low-Dose-Rate Lung Brachytherapy with 125I and 103Pd seeds
Background:Â A new treatment approach for most patients who have undergone early stage non-small-cell lung carcinoma (NSCLC), is wedge resection plus permanent implant brachytherapy. However, the specification of dose to medium at low energies especially in heterogeneous lung is unclear yet.Objective:Â The present study aims to modify source strength for different configurations of 125I and 103...
متن کاملStudy of Different Tissue Density Effects on the Dose Distribution of a 103Pd Brachytherapy Source Model MED3633
Introduction: Clinical application of encapsulated radioactive brachytherapy sources has a major role in cancer treatment. In the present research, the effects of different tissue densities on the dose distribution of a 103Pd brachytherapy source in a spherical phantom of 50 cm radius have been studied. Material and Methods: As is well known, absorbed dose in tissue depends to its density, but ...
متن کاملDetermining TG-43 brachytherapy dosimetry parameters and dose distribution for a 131Cs source model CS-1
Background: Monte Carlo determination of TG-43 brachytherapy dosimetry parameters and dose distribution calculation for 131Cs source model CS-1 are presented in this study. Materials and Methods: The dose distribution was calculated around the 131Cs Model CS-1 located in the center of 30 cm ×30 cm ×30 cm water, and soft tissue phantoms cube using MCNP code by Monte Carlo method. The percentage ...
