Abstract: A CT apparatus includes a plurality of imaging units, a rotation mechanism, a radiation source elevating mechanism, a detector elevating mechanism, and a CPU. The imaging unit includes a radiation source that emits radiation having a quadrangular pyramid shape to a subject and a radiation detector in which a plurality of pixels detecting the radiation transmitted through the subject are two-dimensionally arranged. The rotation mechanism rotates the plurality of imaging units around a body axis of the subject. The radiation source elevating mechanism and the detector elevating mechanism change an interval between the plurality of imaging units in a rotation axis direction. An imaging control unit of the CPU controls operations of the plurality of imaging units, the rotation mechanism, the radiation source elevating mechanism, and the detector elevating mechanism.

Abstract: A radiation source includes a radiation tube having a cathode which is a cold cathode. An imaging control unit directs the radiation source to intermittently and alternately emit the first radiation having a first energy distribution and the second radiation having a second energy distribution different from the first energy distribution whenever a rotation mechanism rotates the radiation source and a radiation detector by a preset angle. The imaging control unit directs the radiation detector to output a first projection image based on the first radiation and a second projection image based on the second radiation which are obtained by the intermittent emission of the first radiation and the second radiation. An image processing unit generates a tomographic image on the basis of the first projection image and the second projection image.

Abstract: A radiation detector has a sensor panel unit which includes two sensor panels and in which end portions of the two sensor panels are arranged to overlap each other in a thickness direction. An image processing unit acquires two projection images from the two sensor panels. A combination unit of the image processing unit performs a process related to image quality on the projection image in a case in which a tomographic image which is a diagnosis image to be used for a doctor's diagnosis is generated and does not perform the process related to image quality on the projection image in a case in which a scout image which is a confirmation image for confirming a reflected state of the subject is generated.

Abstract: A radiation detector includes a sensor panel unit, a support table to which the sensor panel unit is attached, and two fixing members. The sensor panel unit includes two sensor panels. The sensor panel has pixels that sense visible light converted from radiation and generate charge. The sensor panel unit has a configuration in which an end portion of one sensor panel and an end portion of the other sensor panel are arranged to overlap each other in a thickness direction. A first fixing member fixes two sensor panels in an overlap region in which the end portions overlap. A second fixing member fixes the sensor panel unit and the support table in the overlap region. The second fixing member at least partially overlaps the first fixing member in the overlap region in a plan view of the sensor panel unit in the thickness direction.

Abstract: In the radiography system, a camera image of the usage environment in which the electronic cassette is used is captured. An in-image cassette region of the electronic cassette is detected from the camera image. The cassette ID of the electronic cassette is acquired from the in-image cassette region. The acquired cassette ID is collated with the cassette ID of the use cassette set in the console to check whether the use cassette is present.

Abstract: A radiation detector and a radiological image radiographing apparatus capable of improving the quality of an obtained radiological image without causing an additional cost are provided. A first scintillator configured to include columnar crystals generating first light corresponding to a radiation emitted through a TFT substrate is laminated on the other surface of the TFT substrate that has a first photoelectric conversion element, which has one surface from which a radiation is emitted and the other surface from which at least one of the first light and the second light is emitted and which generates electric charges corresponding to the light, and a first switching element. A second scintillator which generates second light corresponding to a radiation emitted through the first scintillator and has different energy characteristics of absorbed radiations from the first scintillator is laminated on a surface of the first scintillator not facing the TFT substrate.
