Patients & VisitorsTokihiro Yamamoto, M.S., Ph.D. 
Clinical/Research Interests
Dr. Yamamoto's clinical interests include image-guided radiotherapy (IGRT) for managing internal anatomy motion during treatment of thoracic and abdominal cancers.
Dr. Yamamoto's main scientific interests focus on advanced anatomic/functional/molecular imaging for improving therapeutic gain of radiotherapy. His current research projects include the development and investigation of novel pulmonary functional imaging techniques based on four- dimensional (4D) computed tomography (CT) and xenon CT (Xe-CT), and applications to lung cancer radiotherapy and beyond.
