- •
Application of Fourier Transform Ultrasound Spectroscopy (FTUS) is demonstrated.
- •
Attenuation constant measured by pulse-echo method depends on experimental conditions.
- •
Intrinsic attenuation constant is determined from Fourier components of echo signals.
- •
Oak Ridge and Oxford method of parameter fitting is applied.
- •
FTUS gives more accurate values for the propagation parameters.
