Claim 9:
10. A system for three dimensional acoustic imaging, comprising:
a computing device comprising a processor and a memory and configured to produce a wide-band composite waveform for transmission toward a biological material of interest, wherein the computing device is operable to produce the wide-band composite waveform by synthesizing a plurality of individual coded waveforms comprising one or both of individual orthogonal frequency-coded waveforms and individual orthogonal phase-coded waveforms, where each individual coded waveform corresponds to a distinct frequency band; and
an array of transducer elements, in communication with the computing device, to transmit a composite acoustic waveform based on the individual coded waveforms of the produced wide-band composite waveform toward the biological material of interest, and to receive returned acoustic waveforms that are returned from at least part of the biological material of interest corresponding to at least some transmitted acoustic waveforms that form the composite acoustic waveform;
wherein the array of transducer elements are configured to receive drive signals based on the individual coded waveforms to drive the transducer elements of the array to form the composite acoustic waveform, and
wherein the computing device is configured to process the received returned acoustic waveforms to produce a three-dimensional image constructed from at least part of the biological material of interest;
wherein the composite acoustic waveform includes one or more amplitudes and one or more phases, wherein the one or more amplitudes are individually amplitude weighted for at least one waveform of the individual coded waveforms and the one or more phases are individually phase weighted for at least one waveform of the individual coded waveforms, thereby providing at least one of steering, focus, or forming of the composite acoustic waveform.
