Addendum to brachytherapy dose‐volume histogram commissioning with multiple planning systems
The process for validating dose-volume histogram data in brachytherapy software is presented as a supplement to a previously published article. Included is the DVH accuracy evaluation of the Best NOMOS treatment planning system called "Best TPS VolumePlan." As done previously in other software, a rectangular cuboid was contoured in the treatment planning system. A single radioactive 125I source...
متن کاملBrachytherapy dose‐volume histogram commissioning with multiple planning systems
The first quality assurance process for validating dose-volume histogram data involving brachytherapy procedures in radiation therapy is presented. The process is demonstrated using both low dose-rate and high dose-rate radionuclide sources. A rectangular cuboid was contoured in five commercially available brachytherapy treatment planning systems. A single radioactive source commissioned for QA...
متن کاملBrachytherapy dose-volume histogram computations using optimized stratified sampling methods.
A stratified sampling method for the efficient repeated computation of dose-volume histograms (DVHs) in brachytherapy is presented as used for anatomy based brachytherapy optimization methods. The aim of the method is to reduce the number of sampling points required for the calculation of DVHs for the body and the PTV. From the DVHs are derived the quantities such as Conformity Index COIN and C...
متن کاملCommissioning of brachytherapy module of Oncentra MasterPlan treatment planning system
PURPOSE To describe the tests that have been performed in order to commission the Brachytherapy module, version 3.2, service pack 3.0, of the Oncentra MasterPlan treatment plan system (OB), from Nucletron. The results were benchmarked against those obtained with the Plato system, v 14.3.7, also from Nucletron, used in the clinical routine. MATERIAL AND METHODS Commissioning was performed taki...
متن کاملData-driven approach to generating achievable dose-volume histogram objectives in intensity-modulated radiotherapy planning.
PURPOSE To propose a method of intensity-modulated radiotherapy (IMRT) planning that generates achievable dose-volume histogram (DVH) objectives using a database containing geometric and dosimetric information of previous patients. METHODS AND MATERIALS The overlap volume histogram (OVH) is used to compare the spatial relationships between the organs at risk and targets of a new patient with ...
