NEW! An Integrated Platform for Patient and Machine QA

Thursday, December 13 // 12 PM U.S. ET

Since implementing the SunCHECK Platform, Wenhuan Jiang, Ph.D., and his team at Swedish Cancer Institute have leveraged SunCHECK Patient as an efficient and reliable tool for linac and IMRT QA, including as a robust method for patient-specific QA. They’ve also performed QA for TG-142 requirements using the SunCHECK Machine capabilities. Join this webinar to hear how they use the complete platform to significantly optimize their clinical workflow.

Multi-Institution Stereotactic QA Results Using SRS MapCHECK™

With the recent release of the SRS MapCHECK™, designed to take the place of film and single point dosimeters in support of small field patient-specific QA, Sun Nuclear aimed to create a device that accurately and efficiently streamlines delivery and analysis. Join this webinar for insights into our process, and hear about lessons learned from measurements taken at 8 institutions across 85 SRS treatment fields.

Integration and Automation of QA in Radiation Oncology

Automation for improved efficiency and consistent analysis, and integration across clinic sites and with modalities—these were the traits the Orlando Health UF Health Cancer Center sought in a modern QA system. In 2017, they implemented SunCHECK™, a fully integrated and independent workflow automation platform for Patient and Machine QA. Join Robert Staton, Ph.D., Senior Medical Physicist, to hear about the advantages his department has gained since implementing SunCHECK.

Replacing Film with an Electronic Array Designed for Stereotactic Patient Specific QA

SRS and SBRT treatments are complex. To efficiently assure quality, an end-to-end testing phantom equipped with an efficient, patient-specific QA tool is desirable. Join Brett Miller, M.S., DABR, of the University of Tennessee Medical Center, for a presentation on his department’s experience replacing film for patient-specific stereotactic QA. He’ll review various solutions available and the implementation of SRS MapCHECK® as a tool of choice.

A Clinically Relevant IMRT QA Workflow: Design, Validation and Implications

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.
