Electromagnetic-guided dynamic multileaf collimator tracking enables motion management for intensity-modulated arc therapy.
PURPOSE Intensity-modulated arc therapy (IMAT) is attractive because of high-dose conformality and efficient delivery. However, managing intrafraction motion is challenging for IMAT. The purpose of this research was to develop and investigate electromagnetically guided dynamic multileaf collimator (DMLC) tracking as an enabling technology to treat moving targets during IMAT. METHODS AND MATER...

PURPOSE To develop a deliverable four-dimensional (4D) intensity-modulated radiation therapy (IMRT) planning method for dynamic multileaf collimator (MLC) tumor tracking delivery. METHODS AND MATERIALS The deliverable 4D IMRT planning method involves aligning MLC leaf motion parallel to the major axis of target motion and translating MLC leaf positions by the difference in the target centroid...
متن کاملA method for determining multileaf collimator transmission and scatter for dynamic intensity modulated radiotherapy.
The main purpose of this work is to demonstrate a practical means of determining the leaf transmission and scatter characteristics of a multileaf collimator (MLC) pertinent to the commissioning of dynamic intensity modulated radiotherapy, especially for the sweeping window technique. The data are necessary for the conversion of intensity distributions produced by intensity-modulated radiotherap...
متن کاملIntensity-modulated arc therapy with dynamic multileaf collimation: an alternative to tomotherapy.
The desire to improve local tumour control and cure more cancer patients, coupled with advances in computer technology and linear accelerator design, has spurred the developments of three-dimensional conformal radiotherapy techniques. Optimized treatment plans, aiming to deliver high dose to the target while minimizing dose to the surrounding tissues, can be delivered with multiple fields each ...
متن کاملPhysics Contribution Integration of Real-time Internal Electromagnetic Position Monitoring Coupled with Dynamic Multileaf Collimator Tracking: an Intensity-modulated Radiation Therapy Feasibility Study
Purpose: Continuous tumor position measurement coupled with a tumor tracking system would result in a highly accurate radiation therapy system. Previous internal position monitoring systems have been limited by fluoroscopic radiation dose and low delivery efficiency. We aimed to incorporate a continuous, electromagnetic, threedimensional position tracking system (Calypso 4D Localization System)...
