PURPOSE This work uses repeat images of intensity modulated radiation therapy (IMRT) fields to quantify fluence anomalies (i.e., delivery errors) that can be reliably detected in electronic portal images used for IMRT pretreatment quality assurance. METHODS Repeat images of 11 clinical IMRT fields are acquired on a Varian Trilogy linear accelerator at… CONTINUE READING
