<P>PROBLEM TO BE SOLVED: To provide a fixed-anode X-ray tube device in which a further increase in the output and a further extension of the service life can be achieved. <P>SOLUTION: The X-ray tube device comprises an envelope inside which vacuum airtightness is maintained; an X-ray tube having a cathode and an anode disposed opposite to each other inside the envelope; a refrigerant for cooling the anode; and a cooler for circulating the refrigerant. The efficiency of the cooler is adjusted in synchronization with X-ray exposure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
