Abstract
A radiographic system is provided that can shorten the work time required for adjusting the initial values. The radiographic system comprises: an X-ray tube controller; an initial value calculator; and a storage. The X-ray tube controller is configured to control a filament current flowing through a filament of the X-ray tube for stabilizing the tube current at a desired value, the tube current otherwise tending to fluctuate at activation. The initial value calculator is configured to calculate an initial value for the filament current that is to be applied at next activation, based both on a stable value of the filament current while the tube current has been stable and on the image-capturing conditions at the time. The storage configured to store the calculated initial value, the image-capturing conditions, and a radiographic history that includes radiographed dates.
