ABSTRACT:
A fluorescence spectrometer for determining a concentration of a photosensitizing drug in a patient, for PhotoDynamic Therapy treatment of the patient by a treatment light at a treatment light wavelength, the fluorescence spectrometer comprising a light source that directs an interrogation beam at a blood or blood plasma sample at an interrogation wavelength range bluer than the treatment light wavelength, measuring a magnitude of an emission signal at the treatment light wavelength, the emission signal caused by the irradiation of the sample, and comparing the measured magnitude to a magnitude/concentration calibration curve to determine the concentration of the photosensitizing drug. A CPU controls the components and makes the comparison and determination.
