Abstract
To understand the physical mechanism behind the bone reconstruction, to predict the
bone loss, and provide test objects for newly developed structural measures we need to
simulate the bone architecture and its evolution. Two features distinguish our bone mod-
eling approach from the results already reported in the literature. First we work with
real bone images, which origin from computed tomography; second, we use structural
measures of complexity to evaluate the bone reconstruction and for comparison with ex-
perimental data. This gives the possibility to test complexity measures by bone modeling,
as well as to test algorithms of bone resorption by comparison with experimentally found
dependencies of structural measures of complexity. In 2D, we generate test objects with
an architecture similar to the trabecular structure of the bone. This analysis shows the
power and efficiency of these measures both in the detection of ordering or disordering
processes, as well as in the detection of small defects. Further on, we have developed algo-
