Paper Abstract

This method is destined for use in connection with photochemotherapy. It consists of two steps: (1) Each tumor is characterized individually by two parameters which are obtained by goniometric measurement of the light crossing a small sample (1 mm3). These parameters can be easily determined in a clinical environment but provide no direct information on the light distribution in the bulk. (2) The above parameters are related with the effective penetration depth for geometries and wavelengths of practical relevance. The relationship is established experimentally by multiple measurements in phantoms which are composed so as to closely approach the optical properties of tumors.
