Abstract
A method of multi-spectral opto-acoustic tomography (MSOT) imaging of a target tissue including a target tissue biomarker includes illuminating the target tissue with an illumination device emitting at least one pulsed illumination pattern at several illumination wavelengths, detecting pressure signals from the target tissue biomarker with a detector device, wherein the pressure signals being produced in the target tissue are in response to the illumination, and reconstructing a quantitative tomographic image of a distribution of the target tissue biomarker in the target tissue, wherein the pressure signals are analyzed using a photon propagation model which depends on an illuminating light fluence in the target tissue and on the illumination wavelengths, at least one spectral processing scheme, and an inversion scheme providing the tomographic image.
