Circular X-ray tube and X-ray a device with circular X-ray tube

摘要

The X-ray circular X-ray tube is formed by a circular body and at least two mutually frictional means of friction forming a triboluminescent X-ray source. The first friction means is formed by at least one circumferential element (3) arranged on the outer peripheral side of the annular tube body (2) and the second friction means is formed by at least one pressing element (4) which is pressed against the peripheral element (3), the pressing element (4) is adapted to slide along the peripheral element (3) and / or the at least one circumferential element (3) is adapted to extend under the pressure element (4). X-rays utilize a circular X-ray tube and ionizing radiation imaging detectors (7).
