Claim Text:
1. A method comprising the steps of: generating a plurality of sinograms, each being generated by sampling a plurality of transducers 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, each transducer being associated with a channel in an optoacoustic imaging system; processing at least two sinograms, each corresponding to a different one of the at least two different predominant wavelengths to create at least two processed sinograms, the processing comprising one or more steps selected from the group consisting of: mitigating anomalous channels, mitigating common mode stripes, bandpass filtering, mitigating the system transfer function, normalization of dynamic range, normalization of energy, removal of interframe persistent artifacts, compensating for hardware time gain compensation, performing sub-band acoustic compensation, and applying a transform operator; performing image reconstruction based upon the at least two processed sinograms to generate at least two optoacoustic images, the image reconstruction comprising one or more steps selected from the group consisting of: extract quadrature, sub-band acoustic compensation, and reconstruction; performing image post processing on the at least two optoacoustic images to generate at least two envelope images, the image post processing comprising one or more steps selected from the group consisting of: removing interframe persistent artifacts, fluence compensation and complex magnitude; generating at least one parametric map based upon the information contained in each of the at least two envelope images; generating an additional parametric map based upon the information contained in each of the at least two envelope images; and, generating a third parametric map, the third parametric map reflective of a combination of information in the at least one parametric map and the additional parametric map.
