QUALITY ASSURANCE SUB-COMMITTEE
The Radiosurgery Society® (RSS) Physics Quality Assurance Sub-Committee was created to expand and promote RSS efforts related to quality assurance to improve radiosurgery delivery. The RSS and its members benefit tremendously from the guidance and insights of our distinguished members who have years of experience in their specialty and are actively involved in the radiosurgery programs at their own institutions.
Dr. Yoo is currently an Associate Professor, director of clinical physics, and director of treatment planning at Duke University Medical Center in Durham, North Carolina. After receiving a PhD in Medical Physics from University of Wisconsin, Madison in 2003, Dr. Yoo joined Radiation Oncology Department at Duke University in 2005. Her special focus is on treatment planning & QA, AI clinical implementation, clinical development of SBRT processes.
Paola Alvarez, MS, is a medical physicist at IROC Houston QA office within the Radiation Physicist Department at MD Anderson Cancer Center since 2002. She is the scientific lead of the external audit program for output check verification. She is also part of the phantom group dedicated to verification of advance technology external beams treatment in radiotherapy.
She is a member of the American Association of Physicists in Medicine AAPM Task Group 178, Task Group 191, Task Group 235 and Task Group 351. She is IROC representative at the Calibration Laboratory Accreditation Subcommittee at AAPM.
Dr. Minsong Cao is a Professor and Director of Dosimetry at the University of California, San Francisco. His primary research interests include image-guided radiotherapy (IGRT), and advanced treatment planning. He has authored over 140 journal articles and six book chapters and has been invited to present at numerous national and international meetings. Dr. Cao has served in many capacities within AAPM, ASTRO, RSS and other organizations and editorial boards of multiple scientific journals. Additionally, Dr. Cao has contributed to expert panels and international guidelines, including NRG Oncology Work Group on State of the Adaptive Radiation Therapy (ART), ASTRO Task Force on Radiation Therapy for Primary Liver Tumors Guideline, AAPM Ad Hoc Committee on Magnetic Resonance Imaging in Radiation Therapy and ICRU Report Work Group on MRI-Guided Radiation Therapy.
Dr. Iris (Zhou) Wang is a Senior Medical Physicist and Associate Professor of Oncology at Roswell Park Comprehensive Cancer Center, where she is also the director of the External Beam Quality Assurance Program. She holds a Ph.D. in Biophysical Sciences from the University at Buffalo (SUNY) and completed her medical physics residency at Roswell Park. With over two decades of experience, Dr. Wang has held faculty and leadership roles at Roswell Park, including serving as Patient Safety Chief for over five years. She specializes in IMRT/VMAT, IGRT, SRS, SBRT, oART, TBI, TSET and brachytherapy, with focuses on quality assurance, accurate radiation treatment delivery, and more recently AI applications in radiation therapy. Dr. Wang is a fellow of the AAPM, an ABR board examiner, an ASTRO APEx site surveyor, and committee member of many organizations such as the RSS, the AAPM and the ABR. She has mentored numerous students, trainees and residents. Her current professional activities and research interests are in the areas of motion management in SBRT, adaptive radiotherapy, quality management and safety, and QA innovations in radiation oncology.
Xiaodong Zhao, PhD, is an assistant professor of the physics division in radiation oncology at Washington University in St. Louis. She completed her B.S. in Physics at Nanjing University, and Ph.D. in Medical Physics at the Louisiana State University. She then completed her Therapeutic Radiologic Medical Physics Residency at the University of Alabama at Birmingham. She joined WashU in 2022. Her primary focus is CT-guided and MR-guided adaptive radiotherapy and Linac-based stereotactic radiosurgery.
