Three-dimensional imaging method for representing structures which cast radiological shadows

摘要

A fluoroscopic apparatus is arranged such that only one cathode ray is directed onto one anode alternately at 2 different positions, the result being the alternating production of 2 X-ray sources at the interpupillary distance. The arrangement is distinguished by a lesser degree of complexity, a lower susceptibility to faults, greater ease of maintenance and lower costs by comparison with previously published designs. The stereoscopic image is perceived by spectacles which, in addition, do not impair normal vision. <IMAGE>
