Abstract
An x-ray positioner is provided having two independently articulated arms supporting an x-ray tube and x-ray detector, respectively, that are mounted offset to the patient and controlled to track a bolus travelling through a patient. A controller is provided with feedback information regarding the bolus to determine the rate of travel, and to produce motion signals to the arms to automatically track the movement of the bolus.
