Seminar Topic: Image-guided therapy with SoniTrack
External Beam Radiation Therapy (EBRT) is used to treat more than half of all cancer patients. In order to improve treatment outcomes, highly potent and accurate radiation doses must be delivered maximize local tumor control and minimize toxicity to surrounding healthy tissue. Anatomy motion during beam delivery poses a fundamental threat to realizing these objectives, and thus restricts the curative potential of EBRT. To address this challenge, SoniTrack Systems is pursuing a novel EBRT image guidance approach in which a custom-designed robotic manipulator and ultrasound probe obtain real-time 3D images during beam delivery. Soft-tissue movements are tracked in ultrasound images and used to guide precise radiation delivery to the moving tumor while avoiding adjacent healthy structures.
Jeff received his PhD in Mechanical Engineering from Stanford University, working with Ken Salisbury in the Salisbury Robotics Lab and Dimitre Hristov in the Department of Radiation Oncology. He is the recipient of an AAPM Young Investigator's Award, an NSF graduate research fellowship, and the Tau Beta Pi Centennial Fellowship. Based on the technology developed during his PhD, Jeff founded SoniTrack Systems, a medical robotics and imaging company that enables radiation delivery for cancer that continuously adapts to anatomy motion. SoniTrack Systems is part of the Stanford StartX accelerator program and has received SBIR/STTR grants from both NIH and NSF.
