Abstract
Systems and methods are described for determining tissue attributes using ultrasound energy. Various characteristics of a medium, such as an animal tissue, can be estimated using techniques such as signal trace analysis and angular-dependency analysis of reflectivity. Such techniques can be performed in conjunction with a spectral decomposition analysis. Attributes can be cross-plotted so as to facilitate user analysis and better understanding of the medium. Attributes obtained in the foregoing manner do not necessarily need to conform to standard values, especially when attempting to detect and characterize an anomaly within the medium. Relative differences of attribute values within the medium can provide information about the anomaly. Additional information about the anomaly can be provided by an observation of the anomaly by an expert.
