Beschreibungen/Notizen

• A device designed to be employed for X-ray transmission difference microscopy and microtomography at the X-ray absorption edges of chemical elements using synchrotron radiation is described. The device comprises a double-crystal monochromator, collimator system, object scanning unit and two X-ray detection blocks based on an NaI(Tl) crystal, photomultiplier (FEU-130) and appropriate electronics. As an example of the practical application of this technique, the first results on the diagnostics of the lymph system by lymphography, i.e. the visualization of the lymph nodes previously contrasted by a Th-containing preparation, are presented. These results have been obtained at the Th L III-edge ( E γ = 16.3 keV using difference microscopy and microtomography.
