Mega‐Voltage Cone‐Beam Computed Tomography (MVCBCT) systems have been in clinical use at UCSF since February 2005. This lecture will provide a general description of the MVCBCT system, image acquisition, reconstruction and registration. The practical clinical applications as well as the guidance strategies will be presented through a number case studies including the following anatomical sites; head&neck, lung, spine, prostate and pelvic sites. Educational Objectives 1. Understand the basics concepts of MV Cone‐Beam CT imaging. 2. Understand the range of clinical applications made possible by MVCBCT in the following categories: a. Patient and organ positioning b. Monitoring of anatomical changes and tumor dose response c. Tomosythesis d. Dosimetric impact e. Dose planning in presence of CT non‐compatible objects f. Brachytherapy g. Dose‐guided radiation therapy (DGRT). This work was supported by Siemens Oncology Care Systems.
