Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical radiography ("diagnostic" and "therapeutic") and industrial radiography. Similar techniques are used in airport security (where "body scanners" generally use backscatter X-ray). To create an image in Conventional Radiography, a beam of X-rays is produced by an X-ray generator and is projected toward the object. A certain amount of the X-rays or other radiation is absorbed by the object, dependent on the object's density and structural composition. The X-rays that pass through the object are captured behind the object by a detector (either photographic film or a digital detector). The generation of flat two dimensional images by this technique is called projectional radiography. In computed tomography (CT scanning) an X-ray source and its associated detectors rotate around the subject which itself moves through the conical X-ray beam produced. Any given point within the subject is crossed from many directions by many different beams at different times. Information regarding attenuation of these beams is collated and subjected to computation to generate two dimensional images in three planes (axial, coronal, and sagittal) which can be further processed to produce a three dimensional image.

An X-ray imaging system is presented that uses multiple pulsed X-ray source pairs in motion to perform efficient and ultrafast 3D radiography. The sources move simultaneously in constant speed as a group on an arc trajectory. Each individual source also moves fast around its static position in a small distance, but one source moves in the opposite direction to another to cancel linear momentum. The trajectories can also be arranged horizontally at a ring structure. In X-ray source pairs, each source part moves in the opposite angular direction to another to cancel angular momentum. The individual X-ray sources are triggered by an external exposure control unit when they have a speed equal to the group speed but in the opposite linear or angular direction. This allows the sources to remain relatively stationary during activation. 3D data can be acquired in a wider field of view in a shorter time, and image analysis is real-time.
