Abstract:
1. A high-voltage apparatus for supplying voltage to a radiation source having a rotating anode, a chamber enclosing the rotating anode, a rotating device for rotating the rotating anode such that a number of rotations of the rotating anode increases to a target value, and a rotation control device for controlling the rotating, anode, the high-voltage apparatus comprising: a voltage applying device for applying a voltage to the rotating anode; and a voltage application instructing device for instructing the voltage applying device to apply a predetermined voltage for enabling radioscopy after the rotation control device starts rotation of the rotating anode; wherein the voltage application instructing device instructs the voltage applying device to apply the predetermined voltage to start irradiation at a time point when the rotating anode reaches a high number of rotations to an extent of being free from damage, said time point being before the number of rotations arrives at the target value.
