Abstract

Measurement of three-dimensional (3D) absorption distribution in a scattered medium is very useful for biomedical applications. Optical coherent tomography (OCT) is a very powerful tool, but the measurement depth is limited to a few mm due to the multiple scattering. Optical diffused tomography (ODT) is alternative method to measure the absorption distribution in deeper depth than that by OCT. In ODT, numerical way is applied to reconstruct a 3D absorption distribution. For successful reconstruction, it is important to develop a way to extract effectively the information of absorbers in output scattered light.
