High-voltage apparatus, and radiation source and radioscopic apparatus having the same

In a high-voltage apparatus according to this invention, a predetermined voltage is applied to a rotating anode after waiting until the number of rotations increases to such an extent that the rotating anode is not damaged. That is, X-rays of desired intensity are already outputted from a point of time when the voltage is applied to the rotating anode. Therefore, diagnosis can be performed immediately after the voltage is applied to the rotating anode. That is, unlike the prior art, there is no need to wait until X-ray intensity becomes suitable for diagnosis after X-ray emission is started, and there is no need to irradiate the patient with unnecessary X-rays. Therefore, the patient can be inhibited from being irradiated with excessive X-rays (with an improvement made in a response from when the operator gives instructions for starting fluoroscopy until emission of X-rays suitable for diagnosis).
