This article reviews the past and current statuses of time-domain near-infrared spectroscopy
(TD-NIRS) and imaging. Although time-domain technology is not yet widely employed due to …

We propose a comprehensive statistical approach describing the penetration depth of light
in random media. The presented theory exploits the concept of probability density function f …

Although numerical methods have been developed for diffusion through single layer
materials, few have been developed for multiple layers. Diffusion processes through a …

The near infrared spectroscopy (NIRS) frequency-domain multi-distance (FD-MD) method
allows for the estimation of optical properties in biological tissue using the phase and …

Spatial neglect is a neuropsychological syndrome in which patients fail to perceive and
orient to stimuli located in the space contralateral to the lesioned hemisphere. It is …

While diffusion has been well studied, diffusion across multiple layers, each with different
properties, has had less attention. This type of diffusion may arise in heat transport across …

The in-vivo optical properties of the human head are investigated in the 600–1100 nm range
on different subjects using continuous wave and time domain diffuse optical spectroscopy …

Red blood cell transfusions are common in patients with sickle cell disease who are at
increased risk of stroke. Unfortunately, transfusion thresholds needed to sufficiently dilute …

This paper is the second of two dealing with light diffusion in a turbid cylinder. The diffusion
equation was solved for an N-layered finite cylinder. Solutions are given in the steady-state …

Accurate and efficient forward models of photon migration in heterogeneous geometries are
important for many applications of light in medicine because many biological tissues exhibit …
