Gafchromic film dosimetry of a new HDR 192Ir brachytherapy source
High-dose-rate (HDR) brachytherapy is a popular modality for treating cancers of the prostate, cervix, endometrium, breast, skin, bronchus, esophagus, and head and neck as well as soft-tissue sarcomas. Because of different source designs and licensing issues, there is a need for specific dosimetry dataset for each HDR source model. The main objective of the present work is to measure 2D relativ...
متن کاملVerification of computerized treatment planning for HDR 192Ir brachytherapy for gynaecological cancer.
Treatment planning in both teletherapy and brachytherapy is time consuming practice but accurate determination of planning parameters is more important. This paper aims to verify the dose delivery time for the treatment of vaginal cancer, which is a vital parameter of High Dose Rate (HDR) brachytherapy treatment planning. Treatment time has been calculated by the computerized treatment planning...
متن کاملComparison of 60Co and 192Ir sources in HDR brachytherapy
This paper compares the isotopes (60)Co and (192)Ir as radiation sources for high-dose-rate (HDR) afterloading brachytherapy. The smaller size of (192)Ir sources made it the preferred radionuclide for temporary brachytherapy treatments. Recently also (60)Co sources have been made available with identical geometrical dimensions. This paper compares the characteristics of both nuclides in differe...
متن کاملHead and neck 192Ir HDR-brachytherapy dosimetry using a grid-based Boltzmann solver
PURPOSE To compare dosimetry for head and neck cancer patients, calculated with TG-43 formalism and a commercially available grid-based Boltzmann solver. MATERIAL AND METHODS This study included 3D-dosimetry of 49 consecutive brachytherapy head and neck cancer patients, computed by a grid-based Boltzmann solver that takes into account tissue inhomogeneities as well as TG-43 formalism. 3D-trea...
