Abstract
We describe a new spectral approach for inversion of photoacoustic data with multi-wavelength pulsed laser illumination. Multi-spectral PAT provides a means of recovery of different chromophore concentrations and ultrasound velocity simultaneously and directly by incorporating prior spectral information into the image reconstruction process. It is demonstrated from simulation tests and small animal experiments that the multi-parameter recovery based on multispectral PAT is reliable and accurate. The reconstructed multiple parameter images may provide us a key tool to quantify physiological function, disease progression, or response to intervention.
