A novel quantitative and reference-free ultrasound analysis to discriminate different concentrations of bone mineral content.

peak1 showed an increasing trend concerning the concentration of particles, thus showing a higher reflection in the case of higher concentrations.

The parameters peak1 and peak2 changed according to an expected trend (see Fig. 6 ): the amplitude of the first reflection increased with increasing concentration due to more significant differences in acoustic impedances, whereas the amplitude of the second reflection decreased with increasing concentration because of less ultrasound energy that crosses the sample.

This metric was able to discriminate most of the tested mineral concentrations, showing a clear trend with respect to the particle concentrations.
