Abstract
An ultrasound method and apparatus for classification of tissue in a region of interest in a body. The raw ultrasound return data is digitized and processed without the need for human visual analysis of pixel-scale video images. Tissue classification is done by correlation of the relative amount of energy in selected frequency bands of the power spectrum of the returned demodulated ultrasound data to that of known tissue samples.
