Abstract
A radiographic examination apparatus improves response to fluoroscopy or continuous shooting by changing promptly the power-output of an X-ray tube. The apparatus and method, when an absolute value of variation C per fixed time interval between the filament electric current of current pulse-output calculated by the filament electric current variation calculation element is more than a setup value, a flash control between pulse conducts increases or decreases temporarily the filament electric current between pulses to become the filament electric current on flash control between pulses calculated by a filament electric current calculation element based on a radiation condition of a current pulse-output and the radiation condition of following pulse-output.
