S. Murty Goddu, PhD is a Professor of Radiation Oncology at Washington University School of Medicine. He earned his BS, MS, and PhD in Physics and Nuclear Physics from Andhra University, India, and completed a residency in medical physics at Washington University. His work focuses on quality assurance (QA) for radiation therapy systems, including linear accelerators, helical tomotherapy, and proton therapy. He has contributed to developing QA tools for 3D-conformal therapy, IMRT, Gamma-Knife, brachytherapy, and radiopharmaceutical treatments. Education: BS, Physics: Andhra University (1983) MS, Nuclear Physics: Andhra University (1985) PhD, Nuclear Physics: Andhra University (1991) Residency, Medical Physics: Washington University School of Medicine (1999) Certifications: American Board of Radiology, Therapeutic Medical Physics (2001) His research emphasizes improving patient safety through QA innovations, such as automated commissioning of radiotherapy systems, electronic chart checks, and deformable image registration. He has published extensively on topics like CBCT volumetric coverage extension , metal artifact reduction , and monitor unit calculations . Selected publications highlight advancements in: Proton therapy commissioning Helical tomotherapy QA Y-90 microsphere delivery protocols Bone marrow radiotoxicity studies Deformable image registration software (DIRART) Multimodality image registration He has collaborated with institutions on clinical trials and protocols for adaptive radiotherapy, dose calculation validation, and patient-specific QA. His work bridges physics, engineering, and clinical oncology to enhance treatment accuracy and safety.
