## Abstract The objective of this study was to develop a light delivery and measurement device for photodynamic therapy (PDT) in the nasopharyngeal cavity, which achieves a homogeneous and reproducible fluence rate distribution to a target area and provides proper shielding of predefined risk areas
A light dosimetry model for photodynamic therapy is described leading to the dependence of necrosis depth on incident light dose. Semiempirical dosimetry relations are derived for four modes of light delivery. Results for PhotofrinB I1 at 630 nm are summarized in graphical form. Numerical values of
## 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 can result in significant damage to the health
