NEW! BEST of 2018 QADS - A Clinically Relevant IMRT QA Workflow: Design, Validation and Implications

Thursday, October 11, 2018 // 12 PM U.S. ET

Different institutions have different methodologies, equipment and criteria for IMRT QA. There is a lot of evidence showing IMRT QA catches large errors, but less evidence for detection of clinically relevant errors. Join Cassandra Stambaugh, Ph.D., Medical Physicist at Tufts Medical Center, as she shares findings on how to determine clinically relevant pass/question/fail criteria for gamma analysis of IMRT QA plans, and how to identify which plans should be further analyzed with DVH metrics. Note: this presentation was presented by Gary Ezzell at QADS 2018. Dr. Stambaugh is a former colleague of Dr. Ezzell at Mayo Clinic.
