Real-time target position estimation using stereoscopic kilovoltage/megavoltage imaging and external respiratory monitoring for dynamic multileaf collimator tracking.
PURPOSE To develop a real-time target position estimation method using stereoscopic kilovoltage (kV)/megavoltage (MV) imaging and external respiratory monitoring, and to investigate the performance of a dynamic multileaf collimator tracking system using this method. METHODS AND MATERIALS The real-time three-dimensional internal target position estimation was established by creating a time-var...

PURPOSE Dynamically compensating for target motion during radiotherapy will increase treatment accuracy. A laboratory system for real-time target tracking with a dynamic MLC has been developed. In this study, the geometric accuracy limits of this DMLC target tracking system were evaluated. METHODS AND MATERIALS A motion simulator was programmed to follow patient-derived tumor motion paths, pa...
متن کاملFirst demonstration of combined kV/MV image-guided real-time dynamic multileaf-collimator target tracking.
PURPOSE For intrafraction motion management, a real-time tracking system was developed by combining fiducial marker-based tracking via simultaneous kilovoltage (kV) and megavoltage (MV) imaging and a dynamic multileaf collimator (DMLC) beam-tracking system. METHODS AND MATERIALS The integrated tracking system employed a Varian Trilogy system equipped with kV/MV imaging systems and a Millenniu...
متن کاملToward submillimeter accuracy in the management of intrafraction motion: the integration of real-time internal position monitoring and multileaf collimator target tracking.
PURPOSE We report on an integrated system for real-time adaptive radiation delivery to moving tumors. The system combines two promising technologies-three-dimensional internal position monitoring using implanted electromagnetically excitable transponders and corresponding real-time beam adaptation using a dynamic multileaf collimator (DMLC). METHODS AND MATERIALS In a multi-institutional acad...
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)...
