Abstract

Frequency-dependent phase velocity measurements may prove useful in bone quality assessment. However, the physical mechanisms of ultrasonic wave propagation in cancellous bone that govern phase velocity are not yet fully understood, particularly the phenomena that lead to the observed anomalous negative dispersion. This chapter provides an overview of phase velocity studies of cancellous bone, especially negative dispersion, and proposals for resolving the apparent conflict with the causality-imposed Kramers-Kronig relations.
