Claim 0:
1. A method for three dimensional acoustic imaging, comprising:
generating a wide-band composite waveform for transmission toward a biological material of interest by synthesizing a plurality of individual coded waveforms comprising one or both of individual orthogonal frequency-coded waveforms and individual orthogonal phase-coded waveform, where each individual coded waveforms corresponds to a distinct frequency band;
transmitting a composite acoustic waveform based on drive signals produced from the individual coded waveforms of the generated wide-band composite waveform toward the biological material of interest, wherein the transmitting includes generating the drive signals based on the individual coded waveforms to drive transducer elements of a transducer array to form the composite acoustic waveform;
receiving 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; and
processing 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.
