A radiographic imaging device includes: a radiation detector including plural pixels, each including a sensor portion and a switching element; a detection unit that detects a radiation irradiation start if an electrical signal caused by charges generated in the sensor portion satisfies a specific irradiation detection condition, and/or if an electrical signal caused by charges generated in a radiation sensor portion that is different from the sensor portion satisfies a specific irradiation detection condition; and a control unit that determines whether or not noise caused by external disturbance has occurred after the detection unit has detected the radiation irradiation start, and if the noise has occurred, that stops a current operation of the radiation detector, and causes the detection unit to perform detection.

Radiographic imaging system comprising an x-ray radiation source. Multiple radiographic imaging apparatuses, each including multiple radiation detecting elements, are arranged two-dimensionally, and configured to read charges generated in the radiation detecting elements as image data and transmit an image signal in response to a command. A console communicating with, controlling with a command the operation of, and receiving image signals from, the multiple radiographic imaging apparatuses and acquires multiple radiographing order information items indicating which of the multiple radiographic imaging apparatuses is to be used for conducting radiographing. Upon receiving the image signal from a first of the radiographic imaging apparatuses, the console determines from the multiple radiographing order information items a subsequent radiographing order item to be conducted by the first radiographic imaging apparatus, and sends a first command to the first radiographic imaging apparatus instructing it to conduct the subsequent radiographing order item.

The planar cassette element includes a hollow cavity disposed on a leading edge thereof and the fabric is configured to dispense from the hollow cavity, surround the planar cassette element and slide about the planar cassette element away from and toward the leading edge of the cassette element. The system allows for easy positioning of the portable x-ray cassette underneath a patient to be x-rayed.

The invention concerns a storage device for cleaning and charging portable X-ray detectors, and an X-ray system comprising such storage device. The storage device comprises a receiving unit for receiving at least one portable X-ray detector, a cleaning unit for cleaning the portable X-ray detector when being received by the receiving unit, and a charging unit for charging the portable X-ray detector, wherein the cleaning unit is configured for mechanically and/or chemically cleaning the portable X-ray detector.

A portable computed tomography (CT) system includes an O-shaped gantry defining an opening, an x-ray source operably coupled to the O-shaped gantry, and a flat panel detector (FPD) coupled to the O-shaped gantry and having a two-dimensional anti-scatter grid (2D ASG) coupled to a side of the FPD facing the opening. With the O-shaped gantry having the FPD, the object may be imaged in a first field of view (FOV) with the detector arranged in a centered geometry. Then, the detector may be arranged in an offset geometry, through-holes of the ASG may be aligned with x-ray emission paths of the x-ray source, and the object may be imaged in a second FOV with the detector arranged in the offset geometry.

A radiography system includes a radiation source that emits radiation, an electronic cassette that receives the radiation and detects a radiographic image, a portable first retainer that holds the electronic cassette, a string that is attached to the first retainer, and a camera that images the string. The first retainer includes a lock portion and a movable portion as an inclination change mechanism that can change an inclination of the electronic cassette with respect to the radiation source. The string and the camera constitute a first detection mechanism that detects an inclination of the electronic cassette about an X-axis which intersects a Z-axis and is directed toward the radiation source in a case in which a radiation detection surface of the electronic cassette and the radiation source are disposed to face each other.

An X-ray imaging system using multiple puked X-ray sources to perform highly efficient and ultrafast 3D radiography is presented. There are multiple puked X-ray sources mounted on a structure in motion to form an array of sources. The multiple X-ray sources move simultaneously relative to an object on a pre-defined arc track at a constant speed as a group. Electron beam inside each individual X-ray tube is deflected by magnetic or electrical field to move focal spot a small distance. When focal spot of an X-ray tube beam has a speed that is equal to group speed but with opposite moving direction, the X-ray source and X-ray flat panel detector are activated through an external exposure control unit so that source tube stay momentarily standstill equivalently. 3D scan can cover much wider sweep angle in much shorter time and image analysis can also be done in real-time.
