Wikipedia
An X-ray tube is a vacuum tube that converts electrical input power into X-rays. X-ray tubes evolved from experimental Crookes tubes with which X-rays were first discovered on November 8, 1895, by the German physicist Wilhelm Conrad Röntgen. The availability of this controllable source of X-rays created the field of radiography, the imaging of partly opaque objects with penetrating radiation. In contrast to other sources of ionizing radiation, X-rays are only produced as long as the X-ray tube is energized. X-ray tubes are also used in CAT scanners, airport luggage scanners, X-ray crystallography, material and structure analysis, and for industrial inspection.
Usage examples of "x-ray tube".
And, in addition, the emanation from radium is steady and constant, whereas the X-ray at best varies slightly with changing conditions of the current and vacuum in the X-ray tube.
Then, using press-button controls suspended from the ceiling by a heavy electrical cord, he maneuvered the heavy X-ray tube along its rollers and downward, until it was immediately above the knee, the arrow on the machine’.
Philips very carefully emphasized that although an X-ray tube was used, the picture that resulted was really a mathematical reconstruction after a computer had analyzed the information.
And that theory also says that tungsten, in an X-ray tube, should radiate in the 'pale pink,' as Morgenthal expressed it.
He shrugged his shoulders and I bit my lip as they shifted me to get the screen and X-ray tube in position.
We rotated the C-arm here and there, continuing to excavate as radiation from the X-ray tube passed through the body and all the muck and charred material surrounding it.
