RADIOGRAPHIC SYSTEM

摘要

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.

1. A radiographic system that performs a radiography with X-rays generated from an X-ray tube based on image-capturing conditions that include an X-ray focal spot size, a tube current, and a tube voltage to be applied between an anode and a cathode in the X-ray tube, comprising:
an X-ray tube controller 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; an initial value calculator 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; and a storage configured to store the calculated initial value, the image-capturing conditions, and a radiographic history that includes radiographed dates.
