Advances in X-ray Technology

A film of carbon nanotubes (as a cathode) that emits electrons at room temperature when exposed to an electrical field has been fashioned into an X-ray device. An array of these emitters can be placed around a target item to be scanned and the images from each emitter can be assembled by computer software to provide a 3-dimensional image of the target in a fraction of the time it takes using a conventional X-ray device. The carbon nanotube emitters also use less energy than conventional X-ray tubes leading to lower operational costs.

Famous quotes containing the words advances and/or technology:

    The Church disowned, the tower overthrown, the bells upturned, what have we to do
    But stand with empty hands and palms turned upwards
    In an age which advances progressively backwards?
    —T.S. (Thomas Stearns)

    The real accomplishment of modern science and technology consists in taking ordinary men, informing them narrowly and deeply and then, through appropriate organization, arranging to have their knowledge combined with that of other specialized but equally ordinary men. This dispenses with the need for genius. The resulting performance, though less inspiring, is far more predictable.
    John Kenneth Galbraith (b. 1908)
