    摘要： Provided are an X-ray imaging apparatus and a consumption level estimation method for an X-ray source, which are capable of estimating the consumption level of an X-ray source without measuring grid voltage.
    An X-ray control part includes: a tube current value setting part for setting a tube current value to be supplied to an X-ray source; a tube current value measurement part that measures a cathode current value as the tube current value by a cathode current detector 15; a time measurement part that measures the time when the tube current value is set by the tube current value setting part and the time when the tube current value measured by the tube current value measurement part reaches the set value; and a consumption level estimation part that estimates the consumption level of a cathode 12 in the X-ray source on the basis of the time until the tube current value reaches the set value after the tube current value has been set.

    摘要： An X-ray imaging system includes an vacuum tube, which is biased by a high voltage power supply connected to the tube by two shielded cables. The cables collectively have a plurality of conductors which are coupled at one end to the high voltage power supply. The other end of each conductor is coupled to a component of the vacuum tube by a separate inductor. During a voltage breakdown of the vacuum tube, the inductors depress electrical current flow between the anode and the cathode of the tube to reduce the erosion of tube components which results from the discharge. This current is in part due to the energy stored in the cable, which is not depressed by conventional current limiting circuits in the high voltage power supply. Voltage limiting devices connected to the tube prevent ringing in the cables from generating excessively high voltage levels.
