PORE SIZE DISTRIBUTION OF HUMAN TRABECULAR BONE – COMPARISON OF INTRUSION MEASUREMENTS WITH IMAGE ANALYSIS
Abstract eng: This paper deals with pore size distribution assessment in trabecular structure of human proximal femur. Two different approaches for estimation of histograms of pore size distribution are tested, mercury intrusion porosimetry and image analysis. For the image analysis two-dimensional images of cross-sections of the specimens were used and the pore size distribution was estimated using a stereological calculation method based on the geometrical properties of an idealized pore. Comparison of the results of both methods is presented. Suitability of both methods for biological materials is discussed regarding to mechanical properties of these materials, characteristics of pores and range of pore sizes present in the structure.
