Physical characteristics of electron beam from conventional and beam shaper IOERT applicator: A comparison study
Introduction: Intraoperative electron radiation therapy (IOERT) is one of the cancer treatment techniques that delivers high doses to tumor bed during surgery. IOERT can be performed by either conventional LINACs or dedicated IORT accelerators such as LIAC (Light Intraoperative Accelerator). Two types of applicators can be used with LIAC dedicated accelerator including conventi...
متن کاملEvaluation of Several Dosimeters for Identification of Irradiated Foods Using a 5 MeV Electron Beam
Electron-beam irradiation facilities are commercially utilized for food irradiation. This study investigates whether dosimeters used to detect gamma-rays can also be used to accurately detect electron-beam irradiation. The irradiation souses for gamma-ray at the Takasaki Institute were used throughout this study. Four kinds of dosimeters, RadiaChromic (RC), GammaChromic (GC), Amber3042 (AM), Ra...
متن کاملIndividual applicator for brachytherapy for various sites of superficial malignant lesions
The aim of this paper is to discuss brachytherapy treatment and individual applicators suitable for unfavorably localized superficial malignant lesions. Techniques for manufacturing an individual applicator and clinical examples of its use for various locations of cancer are presented. This techniques are based on individual size and shape of the tumour. CT-planning make the technique adequate ...
متن کاملDesign of dual scattering foil for 6 to 20 MeV electron beam radiotherapy
The electron beam from the linear accelerator is of size ~ 2 mm, whereas the size of the electron beam profile required for actual treatment is usually larger than 2 2 cm up to 30 30 cm at the iso-center. Therefore, scattering foils were optimized and simulated using FLUKA code. The primar scattering foil as kept niform thickness y w u , whereas the secondary foil was of Gaussian shape with var...
متن کاملBeam characteristics and leakage assessment of an in-house intra-operative electron applicator system
Background: Intraoperative radiation therapy (IORT) technique is used to treat a surgically exposed tumor or tumor bed in the treatment of locally advanced intraabdominal, retroperitoneal, pelvic, thoracic, breast and soft tissue tumors. One way to perform IORT is to use an existing linac and modify the treatment head using an applicator system. In this study the objectives were to design, and ...
