X-ray CT apparatus, X-ray high-voltage device, and X-ray scanning device
First Claim
1. An X-ray CT apparatus comprising:
- an input unit that receives an X-ray irradiation condition for a mounted rotary anode type X-ray tube device;
a starter circuit that supplies driving power for rotating an anode to the rotary anode type X-ray tube device; and
a controller,wherein the controller selects one of predefined two or more types of rating anode rotation speeds depending on the X-ray irradiation condition received by the input unit, instructs the starter circuit to supply driving power for realizing the selected rating anode rotation speed, obtains an arrival time required for a rotation speed of the anode to reach an irradiation possible rotation speed which is lower than the rating anode rotation speed and is required to apply X-rays in the X-ray irradiation condition received by the input unit, and outputs information indicating that irradiation with X-rays is possible to a display unit after the arrival time has elapsed from starting the supply of the driving power by the starter circuit.

Abstract
In order to provide an X-ray CT apparatus which reduces a waiting time period until irradiation with X-rays is permitted with a simple configuration without detecting a rotation speed of an anode, a controller (23) selects a rating anode rotation speed among a plurality of types thereof depending on an X-ray irradiation condition, and supplies driving power for realizing the selected rating anode rotation speed to a stator coil (81) from a starter circuit (10). The controller (23) obtains time required to reach an irradiation possible rotation speed which is lower than the rating anode rotation speed and is required to apply X-rays in an X-ray irradiation condition. If arrival time has elapsed, irradiation with X-rays is permitted. Consequently, it is possible to reduce a waiting time period in which an operator waits for an anode rotation speed to rise.
