Intravenous (IV) catheterization is a medical procedure wherein a metal needle is used to
puncture a vein and introduce a plastic catheter that remains in the vein for the delivery of …

Based on quasi-elastic scattering theory (and random walk on a lattice approach), a model
of laser-Doppler flowmetry (LDF) has been derived which can be applied to measurements …

The rapid development and continuous progress of optical imaging in the medical field
require a profound knowledge of the biological tissue's optical signature. Toward this goal …

Our newly developed method using spatially and time-resolved reflectances can easily
estimate the absorption coefficients of each layer in a two-layered medium if the thickness of …

Two-layered phantom experiments were performed to examine the influence of a fat layer on
measurement of muscle oxygenation using near-IR spectroscopy (NIRS). The phantom …

We try a new approach with near-IR time-resolved spectroscopy, to separate optical signals
originated in the upper layer from those in the lower layer and to selectively determine the …

High accuracy supervised deep learning methods require massive data with accurate
ground truth. However, in biomedical applications, exact measurement of the ground truth is …

Quantitative and accurate determination of turbid media optical coefficients was achieved
using time and space resolved measurements of diffuse backscattered light. The global …

Expanding our previously proposed “time segment analysis” for a two-layered turbid
medium, this study attempted to selectively determine the absorption coefficient (μ a) of the …

In spite of the usefulness of continuous-wave near-infrared spectroscopy (CW-NIRS) for
noninvasive measurement of oxygenation of the brain and muscle, no theoretically derived …
