- 摘要：
PROBLEM TO BE SOLVED: To improve a responding property of fluoroscopic imaging after a second time when carrying out the fluoroscopic imaging intermittently.
SOLUTION: In this X-ray fluoroscopic imaging apparatus, when a fluoroscopic switch is turned off, a filament current of an X-ray tube 1 is maintained in a filament current I3 for main heating at finishing imaging, until a prescribed time T elapses, and a filament heating power source 5b is controlled so as to be switched into a filament current I1 for auxiliary heating after the elapse of the time T. By this, a responding property of a tube current is improved, and an image obtained at the start of fluoroscopic imaging after a second time becomes to have brightness suitable for an immediate diagnosis.
