Automatic IMRT and VMAT Treatment Planning for Head and Neck Cancer

چکیده
The AAPM Professional Liability Insurance program provides a unique ability for medical physicists to obtain liability coverage for risks arising from the practice of medical physics. In the near future, the program is expected to introduce a new occurrence-form coverage option which has important implications and differences from the existing claims-made coverage. Since both forms will be offered to new and renewing policy holders, the intricacies of these two options will be explained. A brief history of the program will be given to review the collaboration between AAPM and its insurance partners that established and maintain the program that is available today.

Using overlap volume histogram and IMRT plan data to guide and automate VMAT planning: a head-and-neck case study.
PURPOSE To investigate whether an overlap volume histogram (OVH)-driven planning application using an intensity-modulated radiation therapy (IMRT) database can guide and automate volumetric-modulated arc therapy (VMAT) planning for head-and-neck cancer. METHODS Based on comparable head-and-neck dosimetric results between planner-generated VMAT and IMRT plans, an inhouse developed, OVH-driven ...
متن کاملMulti-institutional comparison of volumetric modulated arc therapy vs. intensity-modulated radiation therapy for head-and-neck cancer: a planning study
BACKGROUND Compared to static beam Intensity-Modulated Radiation Therapy (IMRT), the main advantage of Volumetric Modulated Arc Therapy (VMAT) is a shortened delivery time, which leads to improved patient comfort and possibly smaller intra-fraction movements. This study aims at a treatment planner-independent comparison of radiotherapy treatment planning of IMRT and VMAT for head-and-neck cance...
متن کاملEfficiency of biological versus physical optimization for single‐arc VMAT for prostate and head and neck cases
The aim of this work was to compare different approaches to VMAT optimization (biological vs. physical DVH-based) in two commercial treatment planning systems (TPS) for head and neck and prostate cases, using Pareto fronts. VMAT vs. IMRT Pareto front comparison was additionally performed in order to benchmark the optimizer efficiency and VMAT plan quality for each TPS. Three prostate and three ...
متن کاملEvaluation of volumetric modulated arc therapy (VMAT) with Oncentra MasterPlan® for the treatment of head and neck cancer
BACKGROUND Several comparison studies have shown the capability of VMAT to achieve similar or better plan quality as IMRT, while reducing the treatment time. The experience of VMAT in a multi vendor environment is limited. We compared the plan quality and performance of VMAT to IMRT and we investigate the effects of varying various user-selectable parameters. METHODS IMRT, single arc VMAT and...
متن کاملDose Distribution Analysis of Rapid Arc and Intensity Modulated Radiotherapy Plan in Head and Neck Cancer
Introduction: Globally, intensity-modulated radiation therapy (IMRT) is considered as highly precise and accurate method of radiotherapy planning. This technique amplifies spatial dose distribution conformity by modulating the intensity of radiation beams in each sub-volume. Additionally, it can reduces the dose to surrounding critical organs and deliver the planned dose to targets with the nom...
