<p><P>PROBLEM TO BE SOLVED: To provide an X-ray tube control method and an X-ray fluoroscopic inspection device obtaining an optimum transmission image by feeding back the transmission image of a specimen and automatically setting an X-ray condition. <P>SOLUTION: The X-ray fluoroscopic inspection device, having an X-ray tube and an X-ray detector detecting the X-ray transmitted through the specimen, forming a transmission image of the specimen depending on the transmission data obtained from the X-ray detector, is composed of an X-ray control part controlling voltage and current of the X-ray tube, an optimum condition estimation means estimating an optimum condition of either the voltage or the current of the X-ray tube which makes the lightness of prescribed two parts on the transmission image T1, T2 turn into aimed values T1aim, T2aim, and a setting means automatically setting the voltage and the current of the X-ray tube by repeatedly feeding the voltage and the current of the X-ray tube back to the X-ray control part according to the above optimum condition. <P>COPYRIGHT: (C)2003,JPO</p> |
