The attenuated ultrasound pulse is divided into two parts: a stationary basic pulse and a nonstationary attenuation pulse. A standard ARMA model is used for the basic pulse, and a nonstandard ARMA model is derived for the attenuation pulse. The maximum likelihood estimator of the attenuated ultrasound pulse, which includes a maximum likelihood attenuation estimator, is derived. The results of this correspondence are of great importance for deconvolution and attenuation imaging in medical… 
Blind deconvolution of ultrasonic traces accounting for pulse variance
A maximum a posteriori algorithm for simultaneous estimation of a time varying pulse and high-resolution deconvolution is proposed and is particularly suited for layered media containing a limited number of abrupt impedance changes.
Minimum entropy deconvolution of pulse-echo signals acquired from attenuative layered media.
The results show that the algorithm, in combination with the attenuation model, yields estimates that reveal the internal structure of the composite and, thus, simplify the interpretation of the ultrasonic data.
On estimating the center frequency of ultrasonic pulses.
It is shown in the paper that the proposed method has less variance than the maximum frequency method, and an upper bound for the variance reduction when practical criteria are applied for fitting the cepstrum cut-off frequency.
A linear model approach for ultrasonic inverse problems with attenuation and dispersion
This paper proposes to exploit a linear model of ultrasonic data taking into account attenuation and dispersion, which outperforms the standard attenuation-free model and other models of the literature.
An adaptive spectral estimation technique to detect cavitation in HIFU with high spatial resolution.
An active spectral cavitation detection method is introduced through a parametric statistical method used on finite-length data sets, which enables local changes to be identified more easily and suggests that good spatial and spectral resolution can be obtained by the design of suitable algorithms.

Processing of ultrasonic grain noise signals for the estimation of depth- and frequency-dependent attenuation
We consider in this paper the general problem of ultrasonic characterization of materials by means of analysing the dependence of attenuation on the frequency and depth of the backscattering noise.
