Abstract: A CT apparatus includes a plurality of imaging units, a rotation mechanism, and a CPU. The imaging unit includes a radiation source and a radiation detector. The rotation mechanism rotates the plurality of imaging units around a body axis of the subject while maintaining a disposition interval. An imaging control unit of the CPU controls operations of the plurality of imaging units and the rotation mechanism. An angular interval that is determined by a frame rate of the radiation detector and a rotation speed of the imaging unit and that defines an acquisition time of a projection image based on the radiation is the same for the plurality of imaging units. The plurality of imaging units have different phases in a rotation direction, and positions where the plurality of imaging units acquire the projection images are separated by a set angle that is less than the angular interval.

Abstract: An overall controller of a console acquires a radiation image of an imaging subject captured by a radiation image capture device for radiographic imaging. The overall controller also acquires body thickness information indicating a body thickness of the imaging subject in a direction in which radiation passes through. The overall controller also adds to the radiation image an assist line image that have would be expected to be obtained if a predetermined member had been disposed and captured at a position inside the imaging subject determined based on the acquired body thickness information, or at a position between the imaging subject and the radiation image capture device.

Abstract: When displaying a stereo image of radiographic images, troublesome work for indicating an abnormal shadow with a three-dimensional cursor is reduced. An abnormal shadow detection unit 8c detects abnormal shadows from radiographic images for left and right eyes for displaying a stereo image. When a plurality of abnormal shadows are detected, an abnormal shadow specification unit 8d specifies abnormal shadows corresponding to each other in two radiographic images. A display control unit 8e gives a three-dimensional cursor to a predetermined abnormal shadow of the plurality of abnormal shadows, and displays a stereo image using the radiographic images for left and right eyes.

Abstract: An X-ray imaging system performs pre-exposure and main exposure to take a single X-ray image. In the pre-exposure, an AEC circuit reads out a dose detection signal outputted from a detection pixel, and compares an integral value of the dose detection signal with a threshold value. When the integral value has reached the threshold value, the AEC circuit stops X-ray emission. A main exposure condition determination unit determines main irradiation time, being one item of a main exposure condition, based on irradiation time in the pre-exposure, an integral dose in the pre-exposure, and a necessary dose required for production of the X-ray image. After that, the main exposure is performed immediately with the determined main irradiation time. Normal pixels perform a charge accumulation operation continuously from the start of the pre-exposure to the end of the main exposure, and the X-ray image is produced from accumulated electric charge.

Abstract: Besides normal pixels, a plurality detection pixels are arranged in an imaging surface of an FPD. In preliminary imaging, X-rays are emitted to an imaged body portion of a patient. The detection pixels receive the X-rays passed through the body portion, and output AEC detection signals. If an integral value of the AEC detection signals has reached a threshold value, X-ray emission is stopped and the preliminary imaging is completed. A main exposure condition determination unit determines a main irradiation time, being an irradiation time with the X-rays during the main imaging, based on an irradiation time with the X-rays during the preliminary imaging and the integral value of the AEC detection signals. The main imaging is performed using the main irradiation time. The normal pixels continue a charge accumulation operation over the preliminary imaging and the main imaging to produce an X-ray image for use in diagnosis.
