We are studying methods for imaging and measurement of micro-structure, components and metabolism in biological body using visible and infrared lights. For example, we measure oxygen saturation of human webbing tissue and blood in micro-circulation, capture the micro-structure of blood vessels using optical coherent tomography, and analyze the characteristics of tumor from Raman spectroscopy.

In addition to the above-mentioned optical measurement, we integrate information from macroscopic modalities such as MRI and CT to aim the improvement of diagnosis performance.

We are interested in image reconstruction or image enhancement of some specific features from a limited number of obtained images or low SNR signals using a priori knowledge and studying the methods for image acquisition and image processing for this purpose.
