Volumetric modulated arc therapy ( VMAT )
New calorimeters Simon Duane, NPL Calorimetry remains the most fundamental method for the measurement of absorbed dose and is the basis of almost all absorbed dose primary standards worldwide. Absorbed dose to water is realised either directly, by using water as the absorbing medium, or indirectly, by using another medium (usually graphite) and determining a factor to convert dose from that med...
متن کاملTreatment planning for volumetric modulated arc therapy.
PURPOSE Volumetric modulated arc therapy (VMAT) is a specific type of intensity-modulated radiation therapy (IMRT) in which the gantry speed, multileaf collimator (MLC) leaf position, and dose rate vary continuously during delivery. A treatment planning system for VMAT is presented. METHODS Arc control points are created uniformly throughout one or more arcs. An iterative least-squares algori...
متن کاملUltrafast treatment plan optimization for volumetric modulated arc therapy (VMAT).
PURPOSE To develop a novel aperture-based algorithm for volumetric modulated are therapy (VMAT) treatment plan optimization with high quality and high efficiency. METHODS The VMAT optimization problem is formulated as a large-scale convex programming problem solved by a column generation approach. The authors consider a cost function consisting two terms, the first enforcing a desired dose di...
متن کاملCommissioning of volumetric modulated arc therapy (VMAT).
PURPOSE Volumetric modulated arc therapy (VMAT) involves the simultaneous use of dynamic multileaf collimator (DMLC) techniques and gantry arcing; appropriate quality assurance is therefore required. This article describes the development and implementation of procedures for commissioning VMAT on a commercial linear accelerator (Elekta PreciseBeam VMAT with MLCi and Beam Modulator heads). MAT...
متن کاملComparison of hybrid volumetric modulated arc therapy (VMAT) technique and double arc VMAT technique in the treatment of prostate cancer
BACKGROUND Volumetric modulated arc therapy (VMAT) has quickly become accepted as standard of care for the treatment of prostate cancer based on studies showing it is able to provide faster delivery with adequate target coverage and reduced monitor units while maintaining organ at risk (OAR) sparing. This study aims to demonstrate the potential to increase dose conformality with increased plann...
