[Quality control of megavoltage cone beam CT imaging system].

Abstract

PURPOSE This paper presents the development of a protocol for quality control of a megavoltage cone beam CT imaging system (MVCB) mounted on a Siemens Oncor 6MV linear accelerator. MATERIALS AND METHODS Several parameters were controlled on the MVCB system: (1) the initial geometric calibration of the system; (2) the quality of the images (geometric… (More)
