In vivo spectrofluorometric anal. during photodynamic therapy (PDT) is a tool to obtain information about fluorophore bleaching kinetics in tissue. Using a cylindrical esophageal light distributor for PDT with an integrated sensing fiber, together with a f ...
BACKGROUND AND OBJECTIVE: Under standardized conditions (drug and light dose, timing), the result of the photodynamic therapy (PDT) of carcinomas of the esophagus with tetra(meta-hydroxyphenyl)chlorin (mTHPC) shows large variations between patients. STUDY ...
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 these va ...

A non-invasive probe has been devised and clinically used to perform in vivo measurements of the optical properties of the esophageal wall and oral cavity. The absorption and reduced scattering coefficients are determined from the observation of the spatia ...
