  • Publication number: 20130077749
    Abstract: A radiation detector is moved along a predetermined axis of movement. Radiation which has passed through a subject is irradiated onto the radiation detector each time the position of the radiation detector changes due to the movement. Signals are read out from the radiation detector each time that radiation is irradiated, to obtain a plurality of radiation images of the subject. Mechanical errors of the radiation detector are detected at each imaging operation, and mechanical error corrected images in which the mechanical errors are corrected are obtained. Amounts of shift of the subject among the mechanical error corrected images are detected, and amounts of movement of the subject during imaging operations are detected based on the amounts of shift.

  • Patent number: 8300764
    Abstract: For a radiographic image detector which includes an imaging plane including two-dimensional matrix of pixel sections, each pixel section storing, when exposed to radiation, a charge according to amount of the radiation, and which is used to be exposed to radiation transmitted through the same subject each time the detector is shifted along a predetermined axis of shift, an inclination of the two-dimensional matrix relative to the axis of shift of the radiographic image detector is detected. The inclination is detected by applying radiation two times to the detector at different radiation application positions effected by the shift of the detector so that a common marker is imaged during each radiation application; carrying out a reading operation after each radiation application to acquire image data representing image information of the marker; and detecting the inclination based on a positional relationship between marker images represented by the image data.
