Abstract

An apparatus and method for reconstructing an acoustic image of an object using a central processing unit programmed to process data derived from acoustic energy that has been transmitted at multiple frequencies and scattered by the object. Electronic signals are propagated at multiple frequencies and transduced into acoustic energy waves which are propagated toward an object. Transducer receivers detect the acoustic energy waves after they have been scattered by the object and the detected acoustic energy waves are then electronically processed and input into a high-speed digital computer which may comprise a central processing unit and/or a central processing unit in combination with an array processor. Data is also prepared and input to the computer representing the incident field and the computer then reconstructs a high-quality image of the scanned object so as to produce an image having high spacial resolution and including actual internal viscous and elastic properties of the object through the use of new inverse scattering techniques used in the data processing steps.
