Charles Geraghty, Clinical Medical Physicist at the Anne Arundel Medical Center in Maryland, US, discusses multileaf collimator (MLC) leakage analysis for quality assurance. He begins by giving an overview of his hospital and the community hospital experience in general. He then discusses the emergence of techniques for treating multiple metastases as well as commissioning measurements. He delves into a study on target separation and the dosimetric effect of rotation and translational errors as well as the importance of MLC leakage in single isocenter multiple metastases treatments. He then discusses MLC leakage modeling with Brainlab Elements Multiple Brain Mets SRS planning software.
