Definitions for x-ray tube
This page provides all possible meanings and translations of the word x-ray tube
a vacuum tube containing a metal target onto which a beam of electrons is directed at high energy for the generation of X rays
A device that produces X-rays by directing energetic electrons into a metal target.
An X-ray tube is a vacuum tube, that produces X-rays. They are used in X-ray machines. X-rays are part of the electromagnetic spectrum, an ionizing radiation with wavelengths shorter than ultraviolet light. X-ray tubes evolved from experimental Crookes tubes with which X-rays were first discovered in the late 19th century, and the availability of this controllable source of X-rays created the field of radiography, the imaging of opaque objects with penetrating radiation. X-ray tubes are also used in CAT scanners, airport luggage scanners, X-ray crystallography, and for industrial inspection.
