Estimating the term…
A computerized three-dimensional x-ray tomographic microscopy system is disclosed, comprising: a) source means for providing a source of parallel x-ray beams, b) staging means for staging and sequentially rotating a sample to be positioned in the path of the c) x-ray image magnifier means positioned in the path of the beams downstream from the sample, d) detecting means for detecting the beams after being passed through and magnified by the image magnifier means, and e) computing means for analyzing values received from the detecting means, and converting the values into three-dimensional representations. Also disclosed is a process for magnifying an x-ray image, and apparatus therefor.
A computerized three-dimensional x-ray tomographic microscopy system comprising in combination a source of parallel x-rays, and sequentially positioned in the path of said x-rays, a monochromator, a collimator, a sample stage, a two-stage asymmetric channel cut x-ray image magnifier, a scintillator, a lens, a charge coupled device, a controller electronically connected to said charge coupled device, an integrating computer electronically connected to said controller, and means for rotating said sample stage in stepwise manner controlled by said computer.
