摘要： Before a radiation image is captured, a rate of change of an output signal from an integrator, during a given period of time after the integrator has been reset and until a radiation start signal is supplied, is calculated. An offset voltage signal at a desired time is calculated using the rate of change, and is supplied to a voltage correcting circuit. An output signal from the integrator after a radiation X has started being applied to a subject is corrected based on the calculated offset voltage signal. The corrected output signal from the integrator is supplied to an X-ray tube controller for controlling application of the radiation X to the subject.

摘要： A radiographic image capturing apparatus includes a radiation source that outputs radiation, a radiation detector for detecting the radiation and converting such radiation into a radiographic image, and a reference point, which is disposed in a removable manner between the radiation source and the radiation detector. The reference point is disposed at the position of a center of rotation of the radiation source, which is set between the radiation source and the radiation detector. By rotating the radiation source about the position of the center of rotation, the radiation source applies radiation with respect to the reference point from at least two different angles.
