Diffuse reflectance spectroscopy: a clinical study of tuberculin skin tests reading
2013
Diffuse reflectance spectroscopy is a technique widely used to determine optical properties of tissues: scattering and
absorption coefficients. In this study, we present the development of a low-cost optical instrument usable in a clinical
environment based upon the spatially resolved diffuse reflectance spectroscopy approach. This instrument has been used in a clinical study to support the diagnosis of tuberculosis. The idea is to establish a new scanning method for an early detection of inflammation due to a reagent injection, before the onset of visual signs. Results comparing the instrumental and classical clinical readings are presented.
