  • Patent number: 11385191
    Abstract: An image acquisition system includes a radiation source configured to output radiation toward an object, a rotating stage configured to rotate the object around a rotation axis, a radiation camera having an input surface to which the radiation transmitted through the object is input and an image sensor capable of TDI control, and an image processing apparatus configured to generate a radiographic image of the object at an imaging plane P based on the image data. The angle formed between the rotation axis of the rotating stage and the input surface of the radiation camera is set in accordance with the FOD which is the distance between the radiation source and an imaging plane in the object. The radiation camera is configured to perform TDI control in the image sensor in synchronization with the rotational speed of the object rotated by the rotating stage.

  • Publication number: 20220141397
    Abstract: An imaging unit includes a housing having a wall portion in which a slit for passing radiation is formed, a scintillator having an input surface to which radiation passing through the slit is input, a first mirror that reflects scintillation light output from the input surface, and a line scan camera that detects scintillation light reflected by the first mirror. The scintillator is placed to make the input surface parallel to both the conveying direction and a line direction. The first mirror is positioned outside an irradiation region connecting the peripheral edge of the slit to the input surface of the scintillator.
