  • Singlet Oxygen Production and Dosimetry for Photodynamic Therapy
    Publication number: 20120209125
    Abstract: An apparatus for photodynamic therapy (PDT) includes a light source configured to provide excitation light for a photosensitizer, an optical system configured to direct the excitation light to a target region and receive light emitted by the photosensitizer and/or singlet oxygen generated in the target region, and a detection system configured to receive the light emitted by the photosensitizer and/or the singlet oxygen. The apparatus also includes a filter system configured to spectrally discriminate between emission from the photosensitizer and the singlet oxygen and a processor configured to determine concentrations of the singlet oxygen and/or the photosensitizer based on an emission signal measured by the detection system.
