ABSTRACT:
A method and apparatus for non-invasively determining a type of tissue and its state within a living entity are disclosed. The method includes the steps of using an imaging technique to generate an image of the tissue matter to be analyzed, selecting a region of interest on the image; positioning a device for transmitting ultrasonic signals at desired frequencies in a desired location relative to the tissue matter; transmitting ultrasonic signals at at least two different frequencies through the region of interest; detecting echo signals reflected by the tissue matter; and analyzing the echo signals to determine attenuation data for the tissue matter. The apparatus includes an imaging device for generating an image of the tissue matter to be analyzed, a device for selecting the region of interest, a device for transmitting ultrasonic signals, a receiver for detecting the echo signals, a display device for displaying the echo signals, and a computer for analyzing and calculating the attenuation data.
