Introduction
Optical tomography uses light in the visible or near-infrared spectral region to illuminate biological objects and build three-dimensional reconstructions of the interior. Because the energy of optical radiation is much lower than existing high-resolution imaging devices based on X-rays, the penetration of light is much lower, and, more importantly, the effect of scattering is much higher. Based on the mean free path of the photons, the physics of light propagation can be considered on different length scales which in turn gives rise to quite different forward and inverse problems. In this entry, we consider the recent development of methods for modeling and reconstruction in the presence of significant scattering, which is described by either transport or diffuse models. For more details, see [2, 4].
Measurements in Optical Tomography
Absorption of light in biological tissue is caused by chromophores of variable concentration such as hemoglobin in its oxygenated and...
