Abstract: Systems and methods are disclosed for performing ultrasound imaging. Channel domain data can be received from an ultrasound transducer to form one or more channel domain data sets. A first ultrasound processing operation can be applied to the channel domain data to generate a first subset of one or more images from the one or more channel domain data sets. A second ultrasound processing operation can be applied to the channel domain data to generate a second subset of one or more images from the one or more channel domain data sets.

Specifically, the attenuation characteristics of the tissue can be estimated using the spectral measurements and known spectral characteristics of the one or more ultrasound signals transmitted into the tissue.

Abstract: Systems and methods for performing diagnostic sonography. Ultrasound information of a subject region can be collected. The ultrasound information can be based on one or more exponentially swept ultrasound chirp pulses transmitted toward the subject region and backscatter of the subject region from the one or more exponentially swept ultrasound chirp pulses. One or more corresponding harmonic responses and a corresponding fundamental response for each of the one or more exponentially swept ultrasound chirp pulses can be separated from the ultrasound information. Further, one or more non-linear properties of the subject region can be identified based on either or both of the one or more corresponding harmonic responses and the corresponding fundamental response for each of the one or more exponentially swept ultrasound chirp pulses.
