Robotic intrafractional US guidance for liver SABR: System design, beam avoidance, and clinical imaging.

Journal: Medical physics
Published Date: Nov 1, 2016

Abstract

PURPOSE: To present a system for robotic 4D ultrasound (US) imaging concurrent with radiotherapy beam delivery and estimate the proportion of liver stereotactic ablative body radiotherapy (SABR) cases in which robotic US image guidance can be deployed without interfering with clinically used VMAT beam configurations.
