Design and Implementation of a Complementary Treatment Planning Software for the GZP6 HDR Brachytherapy System (GZP6 CTPS)
Introduction: Brachytherapy is one of the most common treatment modalities for gynecological cancer. The GZP6 brachytherapy system is one of the devices utilized in Iran. It has been considered particularly due to its low cost compared to other more complete and established systems. This system has some deficiencies including lack of a treatment planning software for non-predefined treatments, ...
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 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...

متن کاملComparison of two planning systems for HDR brachytherapy gynecological application
PURPOSE This report compares the Nucletron NPS and PLATO planning system for patients treated for cervix cancer. MATERIALS AND METHODS This study compares calculations generated using the older NPS (version 11.43) planning system and the more recent PLATO (version 14.1) system for two cases: 1) a single dwell position and 2) an actual patient application using a tandem and ovoid. RESULTS Fo...
