摘要：The article is.to s.udy the development of computer-aided des.g. of X-ray microtomog.aphy—the device for inves.ig.ting.the s.ructure and cons.ruction of three-dimens.onal imag.s.of org.nic and inorg.nic objects.on the bas.s.of s.adow projections. This.article provides.bas.c information reg.rding.CAD of X-ray microtomog.aphy and a s.heme cons.s.ing.of three levels. The article als. s.ows.bas.c relations.of X-ray computed tomog.aphy, the g.neralized s.heme of an X-ray microtomog.aphic s.anner. The methods.of X-ray imag.ng.of the s.atial micros.ructure and morphometry of materials.are des.ribed. The main characteris.ics.of an X-ray microtomog.aphic s.anner, the X-ray s.urce, X-ray optical elements.and mechanical components.of the pos.tioning.s.s.em are s.own. The block s.heme and s.ftware functional s.heme for intellig.nt neural network s.s.em of analys.s.of the internal micros.ructure of objects.are pres.nted. The method of choice of des.g. parameters.of CAD of X-ray microtomog.aphy aims.at improving.the quality of des.g. and reducing.cos.s.of it. It is.s.ppos.d to reduce the des.g. time and eliminate the g.owing.number of eng.neers.involved in development and cons.ruction of X-ray microtomog.aphic s.anners.
