The CT-X tomography technique makes it possible to depict the inner construction o f spatial objects with a precision that permits the execution o f geometric measurements and a quantitative determination o f the density pattern. Owing to the fact that this is a non-destructive technique, it can be applied for examining unique objects such as works o f art. The author worked on a sixteenth-century polychromy linden sculpture and obtained information about: — the technological construction and damage o f the object, — the structure o f the w ood and the state of its preservation, — the effectiveness of the vacuum impregnation of old wood, — the effects o f other conservation operations. An examination o f samples o f several types o f wood enabled the author to establish the scale o f tomographic densities. He also attempted to define the possibility of employing CT-X tomography for dendrochronological measurements. The outcome o f the investigation proved to be extremely valuable for determining the state o f the preservation o f the wooden object, the selection o f a conservation programme and subsequent work. This method allows us to observe the dynamics and effects o f conservation operations. On the other hand, the achievement of valuable results in dendrochronological measurements depended predominantly on the parameters o f the samples. In the case of narrow-ring samples it balanced on the borderline o f the abilities o f the used apparatus (a PICKER SYNERVIEW S.E. medical tomograph from 1988). The basic problem, however, proved to be the lack of opportunities for a direct transference of the results to a generally accessible computer system. This fact adversely affected the precision o f the results and made impossible their complete presentation.
