| Research Abstract |
The algorithms to solve the inverse problems in the optical imaging using near-infrared light for diagnoses of breast cancer were studied. The technique for reconstructing fluorescent light sources in biological media by use of spatial filter was proposed. The method to reduce noise in the time-resolved measurement data using maximum a priori estimation was also developed. The proposed methods were validated with the numerical simulations and the phantom experiments. Efficient arrangement of the light sources and detectors for diffuse optical tomography was also investigated.
