    摘要: In an image processing method of processing an image obtained from an image sensor, the resolution distribution of the image sensor is held in a memory, and a resolution corresponding to a pixel of interest of the image is acquired from the resolution distribution of the image sensor which is held in the memory. Sharpening processing having the sharpening level selected on the basis of the acquired resolution is executed for the pixel of interest.

    摘要: A radiographic apparatus includes a radiation irradiating unit for applying radiation; a radiation imaging unit, including a plurality of imagers, for converting the radiation to image data; a determining unit for determining whether noise caused by residual charge is produced, from the distribution of the residual charge in the radiation imaging unit based on the image data; and a controlling unit for changing a driving state of the radiation imaging unit based on the determination result.

    摘要: In order to remove a scattered line component resulting from an object from projection data to obtain a satisfactory rearrangement image, an amount of scattered line is calculated from a region in which a first-order X-ray is shielded by an X-ray shield and a component corresponding to the scattered line is removed. Then, an image in the region in which the first-order X-ray is shielded is complemented based on an image taken from a 180-degree opposite direction.

    摘要: Since a notification unit (130) notifies a radiographer of the driving state of an X-ray detector (110), he/she can identify that the X-ray detector (110) is set in a detection signal accumulation state. When the irradiation button of an X-ray generation apparatus is then pressed, a subject can be irradiated with X-rays.

    摘要: A radiographic apparatus is disclosed which controls a movement of a reciprocatingly moving grid so that the grid is not or less likely returned in the middle of exposure of an object to X rays. The probability that the object is still exposed to the X rays when the grid is moved in the vicinity of a turning point is thus substantially lowered. Therefore the probability that a resulting radiograph has no or less moire pattern due to the grid is substantially heightened.
