Interactive multiobjective optimization for anatomy-based three-dimensional HDR brachytherapy.
In this paper, we present an anatomy-based three-dimensional dose optimization approach for HDR brachytherapy using interactive multiobjective optimization (IMOO). In brachytherapy, the goals are to irradiate a tumor without causing damage to healthy tissue. These goals are often conflicting, i.e. when one target is optimized the other will suffer, and the solution is a compromise between them....
متن کاملHDR brachytherapy (HDR–BT) combined with stent placement in palliative treatment of esophageal cancer
PURPOSE In the study we present the initial results of palliative treatment using combined methods of HDR-BT and stent insertion in patients with advanced esophagus cancer. MATERIAL AND METHODS Fifty patients were treated in the Great Poland Cancer Center using HDR-BT between June 2001 and December 2005 and they were enrolled into the study. All patients underwent endoscopic insertion of self...
متن کاملAutoactivation of source dwell positions for HDR brachytherapy treatment planning.
The most accurate classical dose optimization algorithms in HDR brachytherapy strongly depend on an appropriate selection of source dwell positions which fulfill user-defined geometrical boundary conditions which are relative to patient anatomy. Most anatomical situations, such as for prostate and head and neck tumors, are complex and can require geometries with 5-15 catheters with 48 possible ...
متن کاملComparison the treatment time of cobalt and iridium sources in HDR brachytherapy
Introduction: The use of long-half-life Cobalt source instead of iridium source will be very helpful in HDR brachytherapy for treatment of cervical cancer. The aim of this study was compared the treatment time with cobalt and iridium source in brachytherapy for treatment of cervical cancer using Tandem-ovoid applicator. Materials and Methods: In this study, 19...
متن کاملMathematical modelling of HDR/PDR brachytherapy treatment planning problems
Brachytherapy is a medical treatment process, based on the use of radioactive sources, which are placed within the patient’s body, in order to submit a curative radiation dose to a target volume. Brachytherapy is mainly used for treating certain kinds of cancerous tumours. It can be considered as an alternative to surgery, and can be used for treating localized tumours. We dress a list of compu...
