Claim One:
1. A method for creating and displaying images in an optoacoustic imaging system, comprising: generating a plurality of multi-channel sinograms, each said channel generated by sampling a transducer acoustically coupled with a surface of a volume for a predetermined period of time after a pulse of light having a predominant wavelength selected from at least two different predominant wavelengths; processing at least two of the plurality of multi-channel sinograms using sub-band acoustic compensation, each of the plurality of multi-channel sinograms corresponding to a different one of the at least two different predominant wavelengths to create at least two processed sinograms, wherein the sub-band acoustic compensation comprises: filtering each of the at least two multi-channel sinograms to create a filtered representation of each of the sinograms; demodulating each said filtered representation of each of the sinograms in the frequency domain; applying a narrowband simplification to each said filtered representation of each of the sinograms to create a processed filtered representation of each of the sinograms, wherein the narrowband simplification is applied in the time domain to the demodulated filtered representations of each of the sinograms; creating two processed images from information contained in each of the processed sinograms; and displaying at least one of the two processed images.
