Original Abstract

The paper studies imaging of tissue-specific ultrasound attenuation. Ultrasound attenuation parameters are closely related to the type and the pathological state of the tissue. Therefore, the estimated attenuation parameters can be used as a feature in quantitative tissue characterization. Ultrasound attenuation is also an important factor affecting spatial resolution of ultrasound images since the higher ultrasonic frequencies are attenuated more than the lower ones. Knowing the attenuation as a function of frequency and depth allows estimation of the depth-dependent point spread function component caused by attenuation. This component can be used to improve the spatial resolution of the ultrasound image through deconvolution.
