Diffuse optical methods constitute a unique and flexible tool to get a non-invasive insight into a number of organs. They offer the possibility to characterize or image (2D,3D) and quantify elementary constituents of biological tissues such as blood (oxy- and deoxyhemoglobin), fat, water, collagen … By accessing to the composition of the tissues, physicians can diagnose a pathology (skin cancer for example) and monitor its evolution.

In this lecture, after an introduction on basics of tissue optics, I’ll briefly formulate the main governing equations of light propagation through biological tissues (forward problem), principles of resolution of inverse problems, and give an overview of some of these techniques (Diffuse Reflectance Spectroscopy, Diffuse Optical Tomography, Polarization gating, Photoacoustics).

Short Biography

Dr Anabela Da Silva is a senior researcher at CNRS (French National Research Center) since 2008, head of the group DiMABio@Institut Fresnel (https://www.fresnel.fr/).
