Dosimetric characterization of a brachytherapy applicator using MCNP5 modelisation and in-phantom measurements.
A gynaecological applicator consisting of a metallic intra-uterine tube with a plastic vaginal applicator and an HDR Ir-192 source have been simulated with MCNP5 (Monte Carlo code). A solid phantom has been designed to perform measurements around the applicator with radiochromic films. The isodose curves obtained are compared with curves calculated with the F4MESH tally of MCNP5 with a good agr...
متن کاملDosimetric Parameters Estimation of I-125 Brachytherapy Source in fat phantom using GATE8.0 code
Introduction: Brachytherapy is one type of internal radiation therapy where radiation sources, which are usually encapsulated, are placed as close as possible to the tumor site or inside the patient's body. In this technique, it is important to determine dose distribution around the brachytherapy capsule to create optimal treatment plant. In this way, dosimetric parameters are...
متن کاملDosimetric optimization of a conical breast brachytherapy applicator for improved skin dose sparing.
PURPOSE Both the AccuBoost D-shaped and round applicators have been dosimetrically characterized and clinically used to treat patients with breast cancer. While the round applicators provide conformal dose coverage, under certain clinical circumstances the breast skin dose may be higher than preferred. The purpose of this study was to modify the round applicators to minimize skin dose while not...
متن کاملDosimetric impacts of applicator displacements and applicator reconstruction-uncertainties on 3D image-guided brachytherapy for cervical cancer
PURPOSE To quantify the dosimetric impact of applicator displacements and applicator reconstruction-uncertainties through simulated planning studies of virtual applicator shifts. MATERIAL AND METHODS Twenty randomly selected high-dose-rate (HDR) titanium tandem-and-ovoid (T&O) plans were retrospectively studied. MRI-guided, conformal brachytherapy (MRIG-CBT) plans were retrospectively generat...
متن کاملDosimetric performance of Strut-Adjusted Volume Implant: a new single-entry multicatheter breast brachytherapy applicator.
PURPOSE To evaluate the dosimetric performance and clinical utility of the Strut-Adjusted Volume Implant (SAVI) (Cianna Medical, Aliso Viejo, CA) applicator when used as the sole method of radiation therapy for patients with early breast carcinoma. METHODS AND MATERIALS The dosimetric performance of a Phase II clinical trial has been reported using the SAVI applicator for patients with early ...
