X-RAY TUBE APPARATUS, X-RAY EXPOSURE DETERMINER, X-RAY GENERATOR USING THEM, AND RADIOGRAPH |
摘要 |
An X-ray tube apparatus (2) having an anode rotating mechanism for preventing damage of the anode (23) of the X-ray tube apparatus thereby to shorten the X-ray exposure waiting time. When the measured number of revolutions of a rotary anode is determined to be predetermined number from only the impedance or current information on the basis of both voltage information and current information on a stator coil (22) of motor constituent elements for rotating the rotary anode, a DC high voltage outputted from an X-ray high-voltage unit (1) is applied between the anode (23) and a cathode (24) of the X-ray tube apparatus, thus exposing a subject (130) to X-rays and imaging the subject. An X-ray generating device and a radiograph are also disclosed. <IMAGE>
