摘要: An X-ray imaging system using multiple pulsed X-ray sources to perform highly efficient and ultrafast 3D radiography is presented. There are multiple pulsed 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.

摘要: A radiographic imaging apparatus includes an electronic cassette and a console device for radio communication with the electronic cassette. The electronic cassette includes a transmitter for transmitting a beacon for the radio communication. A regulation unit regulates beaconing of the beacon in a predetermined specific state among plural operational states. The console device includes a receiver for receiving the beacon. A communication failure detector checks whether a communication failure has occurred in the radio communication according to a receiving state of the beacon in the receiver. A display panel or speaker generates alert notification to notify the communication failure assuming that the communication failure detector judges that the communication failure has occurred. An operational state detector checks whether the electronic cassette is in the specific state. An alert manager avoids generation of the alert notification while the operational state detector judges that the electronic cassette is in the specific state.

摘要: A sensor panel of an electric cassette is provided with detection pixels for AEC to stop X-ray irradiation when an accumulated dose of the X-rays reaches a target dose. A plurality of small blocks each containing a plurality of the detection pixels for calculating the accumulated dose are disposed in each of a plurality of large blocks obtained by dividing an imaging area. The small blocks are disposed so as not to be overlapped with each other in a Y direction.

摘要: The device according to the disclosure is for stabilising a patient in a desired position during X-ray knee imaging. By default, a tibial inclination angle of 10° is envisaged, as according to statistics this constitutes an inclination for the ideal imaging of the knee joint space. This angle as well as the foot rotation angle are adjustable. The device is suitable for a majority of different body heights and shapes. Equipment sensors determine the achievement of the desired position and this is confirmed to the X-ray technician by means of an acoustic and optical transducer.
