Abstract
A method, system, and storage medium for computer aided processing of dual or multiple energy images includes employing a data source, the data source including a dual or multiple energy image set, defining a region of interest within one or more images from the dual or multiple energy image set, extracting a set of feature measures from the region of interest, and employing a feature extraction algorithm on the feature measures for identifying an optimal set of features. The method may be employed for identifying bone fractures, disease, obstruction, or any other medical condition.
