1. A method for estimating ultrasound attenuation coefficient data using an ultrasound system, the method comprising:
(a) accessing with a computer system, ultrasound data acquired from a subject with an ultrasound system, wherein the ultrasound data contain subsets of ultrasound data acquired with different characteristics, wherein the different characteristics result in changes in signal interference patterns between the subsets of ultrasound data;
(b) generating averaged ultrasound data with the computer system by averaging the ultrasound data corresponding to the subsets of ultrasound data;
(c) generating frequency power ratio curve data from the averaged ultrasound data using the computer system, wherein the frequency power ratio curve data have reduced frequency power ratio curve oscillations, wherein the frequency power ratio curve oscillations are reduced based on averaging the subsets of ultrasound data acquired with the different characteristics that cause changes in signal interference patterns between the subsets of ultrasound data; and
(d) generating attenuation coefficient data from the frequency power ratio curve data using the computer system.
