Abstract
A tube voltage control circuitry switches a tube voltage applied to an X-ray tube between a first tube voltage and a second tube voltage of lower value than the first tube voltage. A first signal generating circuitry generates a first switching signal at a first time interval. A view switching circuitry switches a view based on the first switch signal. A data acquisition circuitry performs data acquisition for each view via an X-ray detector. A second signal generating circuitry generates a second switch signal at a second time interval shorter than the first time interval. A gain switching circuitry switches gains of the data acquisition circuitry based on the second switch signal.
