FIELD: medicine.
SUBSTANCE: invention relates to medical equipment, namely to X-ray devices and methods of obtaining X-ray images. Method lies in application of detector and distributed structure of X-ray irradiation sources, uniformly distributed with common pitch with respect to each other and movement of distributed structure of X-ray irradiation sources and/or detector relative to visulisation volume. Maximal distance dmax of distributed structure movement is limited by length of pitch lp, with movement rate changing in accordance with saw-like or sinusoidal law. The study of distributed structure of sources and generation of multitude of response signals on detector takes place during movement. Method is realized by system of X-ray visualisation, containing detector and distributed structure of X-ray irradiation sources.
EFFECT: application of the invention makes it possible to achieve considerable spatial resolution and image quality, as well as to reduce scanning time.
