Gamma Knife Education & Training

Washington Hospital is the first hospital in the United States that treated patients using the new Leksell Gamma Knife Perfexion®, a revolutionary alternative to traditional open-brain surgery and/or daily radiation treatments, which are administered from four to six weeks.

Washington Hospital is offering a Physics Course, twice a year, to provide training for stereotactic radiosurgery utilizing the Leksell Gamma Knife® Perfexion™.

Course Directors

Washington Hospital's Gamma Knife Program is led by one of the most accomplished teams of specialized physicians, physicists and nurses. Neurosurgeon Sandeep Kunwar, MD, co-medical director, Gamma Knife Program, Taylor McAdam Bell Neuroscience Institute and radiation oncologist David Larson, MD, PhD, co-medical director, Gamma Knife Program, Taylor McAdam Bell Neuroscience Institute are both nationally and internationally recognized for their expertise, innovation and leadership in the field of Gamma Knife radiosurgery. Dr. Larson was a close advisor to Elekta in the design and development of the Gamma Knife® Perfexion™. Both board-certified physicians, together they have more than 23 years of experience performing thousands of successful procedures. Paula Petti, PhD, radiological physics, director of Gamma Knife Physics, Taylor McAdam Bell Neuroscience Institute, is board certified in therapeutic radiological physics. Her areas of expertise include: stereotactic radiosurgery, charged-particle radiation therapy, Monte Carlo calculations, as well as particle and photon dose calculations.

Washington Hospital Healthcare System will meet all requirements on disclosure, information about relationships of presenters with commercial interests (if any) will be included in materials, which will be distributed at the time of the conference.
