1. A method for creating and displaying images in an optoacoustic imaging system, comprising the steps of: generating a plurality of multi-channel sinograms, each channel being 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, each corresponding to a different one of the at least two different predominant wavelengths to create at least two processed sinograms, the step of processing each of the two multi-channel sinograms comprising sub-band acoustic compensation, wherein the step of sub-band acoustic compensation comprises: establishing a filter bank of sub-band filters, the filter bank defining a plurality of sub-bands of the frequency domain; applying the filter bank to each of the at least two multi-channel sinograms to create a filtered representation of each of the sinograms for each sub-band filter; applying a narrowband simplification to each filtered representation of each of the sinograms for each sub-band filter to create a processed filtered representation of each of the sinograms for each sub-band filter; reassembling the processed filtered representation of each of the sinograms for each sub-band filter to produce an acoustically compensated sinogram for each of the at least two multi-channel sinograms; demodulating each filtered representation of each of the sinograms in the frequency domain prior to applying the narrowband simplification; wherein the narrowband simplification is applied in the time domain to the demodulated filtered representations of each of the sinograms for each sub-band filter; creating the at least two processed sinograms based upon the acoustically compensated sinograms; creating two processed images from information contained in each of the processed sinograms; and displaying at least one of the two processed images.
