Abstract
A non-invasive bone condition data acquisition system performs sensitive and reliable clinical data acquisition, localization and classification of bone disease, particularly osteoporosis. The bone condition data acquisition system measures a correlation between a wideband AE signature and a spatially localized bone microarchitecture, which is used to determine fracture risk. The bone condition data acquisition system includes processors and memory for analyzing AE signals from bone tissue to generate information-bearing attributes, for extracting a set of times-of-arrival and a feature vector from the attributes, for utilizing the set of times-of-arrival to derive the locations of the AE events, and for responding to the feature vector to classify the bone using a neural network and a nearest neighbor rule processor.
