Diffuse reflectance spectra were collected from adenomatous colon polyps (cancer
precursors) and normal colonic mucosa of patients undergoing colonoscopy. We analyzed …

Colorectal surgery is the standard treatment for patients with colorectal cancer. To overcome
two of the main challenges, the circumferential resection margin and postoperative …

The spectral reflectance of the colon is known to be affected by malignant and pre-malignant
changes in the tissue. As part of long-term research on the derivation of diagnostically …

In this letter, we report the first use of oblique incidence diffuse reflectance spectrometry to
conduct in-vivo measurements of optical properties of three different types of pigmented skin …

Diffuse reflectance spectroscopy of colonic tissue was employed to determine whether the
spectra can be used to distinguish between neoplastic and non-neoplastic tissue in vivo. A …

A noninvasive method to measure the optical properties of a diffusing and absorbing
medium is described. Based on the spatially resolved measurement of diffuse reflectance at …

Spatially resolved reflectance measurements are widely used for determination of the optical
properties of biological media. However, the influence of the phase function on these …

Determination of tissue optical properties is fundamental for application of light in either
therapeutical or diagnostics procedures. In the present work we implemented a spatially …

Monte Carlo simulations and experiments in tissue phantoms were used to empirically
develop an analytical model that characterizes the reflectance spectrum in a turbid medium …

Diffuse-reflectance spectroscopy for measurement of the absorption and scattering
coefficients of biological tissue produces reliable results for wavelengths from 650 to 1050 …
