Description
上記課題を解決するため、本発明のＸ線ＣＴ装置は、交流電源とＸ線管との間に、互いに並列に複数の直流電圧発生装置を接続するとともに、各直流電圧発生装置とＸ線管との間に、それぞれ、スイッチング手段を備える。好適な態様において、スイッチング手段の一つは、ダイオードで置き換えることができ、ダイオードは複数の直流電圧発生装置のうち、最も出力電圧の小さい直流電圧装置とＸ線管との間に挿入される。 In order to solve the above problems, an X-ray CT apparatus of the present invention connects a plurality of DC voltage generators in parallel with each other between an AC power source and an X-ray tube, and each DC voltage generator and X-ray tube. in between, it respectively, provided with a switching means. In a preferred embodiment, one of the switching means can be replaced with a diode, and the diode is inserted between the DC voltage device having the lowest output voltage and the X-ray tube among the plurality of DC voltage generators.
