PURPOSE: To easily perform maintenance on a power supply means and to improve reliability for the whole system by providing the power supply means with a non-contact feed means in an X-ray CT system equipped with a means to supply the power from a power source to an X-ray tube side in a scanner rotating part rotating successively.
CONSTITUTION: An electromagnetic induction supply means 19 formed by combining a first coil 20a connected to the output side of an inverter 2 and arranged at the fixed frame of a scanner and divided into plural coils, and a second coil 20b arranged confronting with the first coil 20a and connected to the input side of a high voltage transformer 3 and divided into plural coils is installed as the means which supplies the power from the power source 1 disposed at the scanner rotating part 8 to the X-ray tube 5 side. In this way, a required power is supplied in non-contact fashion by an electromagnetic induction function, and a power supply part is prevented from wearing or corroding, and the maintenance of the power supply means is facilitated, and also, the reliability for the whole system is improved.
