The article presents the possibilities and effects of the application of computer tomography for research into the structural impregnation of wooden historical objects. The herefore employed research methods do not provide full information as regards the obtained degree of impregnation, participation and arrangement of the material in the porous structure of the impregnated object. Their fault lies in the fact that apart from insufficient ineffectivennes and complicated technique, those methods are highly destructive and fragmentary, calling for cutting or taking samples of the material under examination. By way of contrast, computer tomography, used for the first time in Poland, gives a chance for studying the process of impregnation together with the accompanying changes in the structure on one material. At the same time, it enables to obtain a visual picture and quantitative estimation of those changes in the whole structure, in a way which is non-destructive and offers a practical estimation of the effects of impregnation on an arbitraily chosen part of the historical object. With this methods, the usefulness of chosen thermoplastic material - Winacet R-50, Osolan KL, Osolan К and Paraloid B-72 - was judged for reinforcing impregnation, by basing ourselves on their allocation in limewood, under certain conditions created by the impregnation technology. The interesting possibilities of computer tomography were also used in research concerning the polychrome wooden sculpture „King Casimir the Great” (1380) in the Jagiellonian University Museum in Cracow, which was impregnated in a vaccuum with a 20 per cent solution of Paraloid B-72 in xylene.
