Conclusions
-
1.
Ultrasound measurements employing piezoelectric transducers with exponential waveguides may be used for studying the structural features of bones.
-
2.
The isorapid zones of large tubular bones, specifically, the tibia, femur, and humerus, have a pronounced orientation with predominantly transverse extension in the epiphyses, longitudinal spiral configuration in the diaphyseal segment, and dentate pattern in the transition region.
-
3.
Acoustic plateau regions are found in the zones for the attachment of the large crural muscles with relatively low gradient of ultrasound velocity change.
-
4.
The transverse acoustic rigidity varies in magnitude, transverse configuration, and orientation relative to the major axes of the geometrical cross section of the bone over its length.
