Abstract:
Medical imaging is indispensable in modern medicine. To overcome various problems of current imaging techniques such as X-ray, MRI, PET, etc., we are developing an optical transillumination imaging technique. With visible light, we can see only the surface of our body. In contrast, near-infrared light with 700-1200 nm wavelength has relatively high transmission through animal tissue. However, the strong optical scattering in the tissue makes transillumination imaging difficult. If we can appropriately handle this scattering effect, we can see through our body without using hazardous X-ray. Moreover, using the rich legacy of optical spectroscopy, we can realize various functional imaging and molecular imaging for the three-dimensional internal structure of an animal body.
