Photodynamic therapy (PDT) has had mixed reception in the clinic, with most success stories being based on the ablative capacity of PDT. In these applications, maximal combinations of light and an exogenous photosensitiser are used to generate high l

BACKGROUND AND OBJECTIVE: A technique to manufacture a stable, reproducible three-dimensional optical phantom is presented. This phantom reproduces the tissue's optical properties as well as the geometry and, to some extent, the mechanical properties

BACKGROUND AND OBJECTIVE: Photodynamic therapy (PDT) is an efficient technique to treat superficial early cancers in the pharynx, esophagus, and tracheo-bronchial tree. However, the lack of selectivity of some of the clinically used photosensitizers

Background. To optimize photodynamic therapy (PDT) and photodetection of cancer, two important variables that must be considered are the uptake of the dye and the dye contrast between normal and neoplastic tissue after injection. Methods. To study th

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 the sample surface, this method is particularly suitable for investigating

Light propagation in two-layered turbid media having an infinitely thick second layer is investigated in the steady- state, frequency and time domains. A solution of the diffusion approximation to the transport equation is derived employing the extra

A noninvasive probe has been devised and clinically used to perform in vivo measurements of the optical properties of the esophageal wall. The absorption coefficient and the effective scattering coefficient are determined from the observation of the

A brief overview is given of light distributors developed by our group in Lausanne for photodynamic therapy (PDT) of cancer. We focus on fiber optic devices which have to a large extent been tested over the years in the clinic for PDT of the upper ae
