X-RAY CT DEVICE

WIPO Patent Application WO/2010/026914

A1

In order to provide an X-ray CT device that makes high-speed scanning possible by providing a non-contact power transmission means and signal transmission means between a scanner stator and scanner rotor, a non-contact power transmission means, which transmits without contact the output power of an inverter circuit to a scanner rotor, and a non-contact signal transmission means, which transmits without contact a control signal for the control of tube voltage and/or tube current to a scanner stator, an anode drive control signal that controls rotation of an X-ray tube anode, and X-ray detection data that has been detected by an X-ray detector are disposed between the scanner stator and scanner rotor in the X-ray CT device, which is also equipped with a tube voltage preset means, which applies a tube voltage, which does not contribute to X-ray generation, to the X-ray tube, and a tube voltage control initiation means, which starts control of the set tube voltage from a state in which the tube voltage has been preset.
