[Mechanical changes in bone after roentgen irradiation with low dosage].

We investigated the micromechanical properties using doses from 1 up to 7 Gray and could observe a roughening on the surface of the bone material in the microscopic range by scanning acoustic microscopic measurements. In addition, a preceding irradiation promoted an extension of microcracks during the polishing process indicating an embrittlement. After irradiation and removal of the surface layer, the SAM measurements indicate a preferential increasing of hardness of softer regions. These results are consistent with our measurements by environmental scanning electron microscopy.

Quantitative measurements of the mechanical properties of human bone tissues by scanning acoustic microscopy.

The quantitative scanning acoustic microscopy is used for determination of the acoustic impedance of human femoral bones in the micrometer scale. The method is introduced and demonstrated at prepared bone surfaces with different cutting angles referring to the bone axis. First measurements show weak variations of the elastomechanical properties with angles.
