Ct simulation images
WebRespiratory motion management simulation is typically performed when there is a need to account for the breathing-related motion of pulmonary or abdominal tumors that will be targeted with radiation therapy. The work involves acquisition and review of multiple additional CT images that allow for a full accounting of breathing-related tumor motion.
