The Washington Radiation Oncology Center (ROC) is part of our cancer care affiliation with UCSF. Local residents are able to received academic-level care without traveling across the bay. The center maintains a caring and compassionate atmosphere, utilizing state-of-the art technology—including the new linear accelerator—while benefiting from cancer research done at UCSF.
The linear accelerator uses sophisticated imaging to conform to a tumor’s shape and destroy cancer cells while sparing surrounding healthy tissue. It features several built-in safety measures to ensure that it will deliver the precise dosage.
According to the ROC medical director, Dr. Emi Yoshida, “Our new linear accelerator offers a broad range of treatment techniques that have incredibly high degrees of precision, accuracy, and speed. This means patients will spend less time on the treatment table every day. Our new system also has more advanced imaging capabilities that enable us to make fine-tuned adjustments on a daily basis.”

These resources allow the ROC to develop treatment plans based on three-dimensional images of the tumor and surrounding tissue. A dose of radiation can then be prescribed and delivered with multidirectional beams that not only improve the accuracy and effectiveness of the treatment but also limit the dose and minimize injury to the surrounding tissues.
Experienced Staff
Our multidisciplinary team of healthcare professionals are highly committed to maintaining a quality, state-of-the-art cancer treatment facility. Our experienced staff at the center includes three board-certified radiation oncologists, three licensed radiation therapists, a medical physicist, a licensed dosimetrist, licensed nurse navigator (RN) and a manager.
Emi Yoshida, MD
Dr. Yoshida earned her medical degree from the University of California, Davis, and completed her residency at Cedars-Sinai in Los Angeles, CA. She is an assistant professor in the Department of Radiation Oncology at UCSF and is on the faculty at UCSF Health, while also treating patients at the Washington Radiation Oncology Center.
Nicolas Prionas, MD, Ph.D.
Dr. Prionas earned both a bachelor’s degree in biomedical computation and a master’s degree in biomechanical engineering from Stanford’s School of Engineering. He then enrolled in an eight-year “dual-doctorate program” at the University of California, Davis, in which he earned both his Ph.D. from the School of Engineering and his MD from the School of Medicine. Dr. Prionas completed his Radiation Oncology Residency training at Stanford University.
Jesse Alexander, MD, Ph.D.
Dr. Alexander earned a Ph.D. in biology at the Massachusetts Institute of Technology and his medical degree from the Duke University School of Medicine. He completed his residency in radiation oncology at the University of California, San Francisco.
Washington Hospital is a designated Radiation Oncology Center of Excellence
by the American College of Radiology (ACR). By awarding facilities the
status of a Radiation Oncology Center of Excellence, the ARC recognizes
a facility that has gone through a comprehensive review process overseen
by board-certified, expert radiation oncologists and medical physicists.
