BIOLOGICAL MEASURING APPARATUS AND BIOLOGICAL MEASURING METHOD

摘要

A biological measuring apparatus measures physical parameters in a part of a living body by diffuse optical tomography. The apparatus includes at least one first light source and one first detector both disposed inside the living body, at least one second light source and one second detector both disposed outside the living body. A processor processes measured values and reconstructs the distribution of scattering coefficients or absorption coefficients of light interacting with the living body. The measured values are acquired from at least one measurement light beam emitted from the first light source and detected by one of the first and second detectors, and at least one measurement light beam emitted from the second light source and detected by one of the first and second detectors.
