Abstract
Parallel/Opposed: IMRT QA using treatment log files is superior to conventional measurement-based method.
Highlights
In the recent years, more and more researchers believe measurement-based quality assurance (QA) method for intensity-modulated radiotherapy (IMRT) is insensitive in detecting various types of failures.[1,2,3] Machine delivery log-file analysis has been proposed to be a more effective and efficient approach in verifying IMRT delivery accuracy in terms of gantry, collimator, jaws, and MLCs.[1,4,5,6,7,8,9] whether log file measurements can replace conventional QA methods remains a major debate in current medical physics society
His dissertation focused on bulk IMRT QA analysis and film dosimetry
It is important to note that log file-based IMRT QA must be augmented with independent commissioning measurements and a robust routine QA program to verify machine calibration
Summary
More and more researchers believe measurement-based quality assurance (QA) method for intensity-modulated radiotherapy (IMRT) is insensitive in detecting various types of failures.[1,2,3] Machine delivery log-file analysis has been proposed to be a more effective and efficient approach in verifying IMRT delivery accuracy in terms of gantry, collimator, jaws, and MLCs.[1,4,5,6,7,8,9] whether log file measurements can replace conventional QA methods remains a major debate in current medical physics society. Dr Nathan Childress (Mobius Medical Systems, LP) The goal of IMRT QA is to ensure each patient receives safe and effective treatment. Can log file-based IMRT QA verify information transfer integrity and delivery performance, it can do so more accurately and efficiently than conventional methods.
