Kononov, S. Ignatov, V. Potapov, V. Negorezov] A system for detecting X-ray shadowgraphs with a high spatial resolution, in which a shadowgraph formed on a luminophor is transferred to a charge-coupled device (CCD) matrix by using an objective lens, is considered. The signal stored on the CCD matrix is read, converted, and transmitted to the computer for further processing and representation. A 25-lp/mm spatial resolution was obtained for a 10.8 × 10.8-mm input field of the system. The measurements were performed by using a tungsten-wire standard placed on the surface of the input field of the detecting system, when the anode voltage was 45 kV, the anode current was ∼2 mA, and the focal distance was 450 mm. It was shown that the 25-lp/mm spatial resolution is not limiting and that it is possible to attain a value of 40 lp/mm or higher. Pleiades Publishing, Inc., 2006 87.59.-e nationallicence Kononov N.
