Photoacoustic tomography reconstructing absorption coefficient and effect of regularization minimizing p-norm

Photoacoustic (PA) tomography can be useful to measure the hemoglobin concentration in blood vessels and tissues, and provide important information to determine the course of treatment for hypoxic malignant cancer which possesses the resistance to treatment. To image the hemoglobin concentration and oxygen saturation, the reconstruction of absorption coefficients at multiple wavelengths is required to correct the penetration depths of the multiple wavelengths of light. In this study, the authors tried the image reconstruction of the absorption coefficient for various concentration of photon absorber. Additionally, the effects of the regularizations minimizing 1-norm and p-norm (0
