Medical imaging based on near infrared (NIR) illumination is a powerful and cost-effective approach for characterizing thick tissues. Technological developments using principles of Diffuse Optical Spectroscopy (DOS), Diffuse Optical Imaging (DOI), Diffuse Optical Tomography (DOT), and Diffuse Correlation Spectroscopy (DCS) have helped drive significant advances.

Light reflectance spectroscopy (LRS) is a multispectral technique, sensitive to the absorption and scattering properties of biological molecules in tissues.

It is used as a noninvasive tool to extract quantitative physiological information from human tissues and organs. A near-infrared LRS based on a single optical probe was used to monitor changes in optical and hemodynamic.

Proc. SPIEOptical Tomography and Spectroscopy of Tissue X, I (25 March ); doi: / Read Abstract + A Gen-2 hand-held optical imager has been developed capable of 2D surface imaging and 3D tomography.

About this book This entry-level textbook, covering the area of tissue optics, is based on the lecture notes for a graduate course (Bio-optical Imaging) that has been taught six times by the authors at Texas A&M University. Diffuse correlation spectroscopy (DCS) is an optical modality used to measure an index of blood flow in biological tissue.

This blood flow index depends on both the red blood cell flow rate and density (i.e., hematocrit), although the functional form of hematocrit dependence is not well delineated. Herein, we develop and validate a novel tissue-simulating phantom containing.

Diffuse optical techniques utilize light in the near infrared spectral range to measure tissue physiology noninvasively. Based on these measurements, either average bulk optical properties or three‐dimensional spatial maps of tissue properties such as total hemoglobin concentration, blood oxygen saturation and scattering can be obtained using.

Optical coherence tomography (OCT) is an imaging technique that uses low-coherence light to capture micrometer-resolution, two- and three-dimensional images from within optical scattering media (e.g., biological tissue).

It is used for medical imaging and industrial nondestructive testing (NDT). Optical coherence tomography is based on low-coherence interferometry, typically.

In this study we introduce an imaging device combining optical coherence tomography (OCT) and Raman spectroscopy (RS), allowing to record 2D and 3D OCT cross sectional images of bulk tissue samples, as well as the acquisition of Raman spectra from small areas of interest in order to aid the detection process with molecular information.

[Britton Chance; Society of Photo-optical Instrumentation Engineers.;]. These optical properties are parameters in the radiation transport equation which describes the propagation of light in tissue (see Chapters 2, 3, and 6).

Another parameter often measured is the effective attenuation coefficient, µ eff, which describes the exponential attenuation of scattered light with depth in tissue. Abstract. Substantial progress in the field of light spectroscopy and imaging of tissues was achieved when the group of Chance, Patterson and Wilson showed that the optical parameters of a turbid medium can be obtained from time resolved measurements of short light pulses propagating in the medium (Patterson et al, a).

It was found (Benaron, in Caro and Choy, ; Hebden et al., ; Wilson et al., ) that one could use these methods for optical spectroscopy and for imaging of tissue. In spectroscopy both reflectance and absorption measurements can be performed and can be used for quantitative measurements on tissue, such as the hemoglobin oxygen saturation.

We hypothesize that diffuse optical tomography imaging provides quantitative measurements of tissue functional components, such as ctO 2 Hb, which is directly related to tissue metabolism and vascular characteristics, and could be correlated to mammographic breast density, a known imaging biomarker of breast cancer risk.

In addition, we. the optical penetration depth on the absorption and reduced scattering coefficients should be carefully considered in the quantitative analysis of the optical spectra of tissues. Keywords: tissue spectroscopy, tissue inhomogeneity, hemoglobin saturation, arm ischemia.

Bone. Time-domain diffuse optics or time-resolved functional near-infrared spectroscopy is branch of functional near-Infrared spectroscopy which deals with light propagation in diffusive media.

There are three main approaches to diffuse optics namely continuous wave (CW), frequency domain (FD) and time-domain (TD). Biological tissue in the range of red to near-infrared. Dear Colleagues, Optical imaging and characterization of tissue has become a huge applied field due to the advantages of the optical analysis methods, which include non-invasiveness, portability, high sensitivity, and high spectral specificity.

The ablation surfaces were studied by scanning electron microscopy, grazing incidence x-ray diffraction, and micro-Raman spectroscopy. Regardless of the fluence, the ablation surfaces were covered by a layer of resolidified material, indicating that ablation is accompanied by melting of hydroxyapatite.
