Dosimetry for photodynamic therapy (PDT) is becoming increasingly complex as more
factors are identified which may influence the effectiveness of a given treatment. The simple …

We describe three lessons learned about how tissue optics affect the dosimetry of red to
near-infrared treatment light during PDT, based on working with Dr. Tayyaba Hasan. Lesson …

Photodynamic therapy (PDT) is an emerging treatment modality that employs the
photochemical interaction of three components: light, photosensitizer, and oxygen …

Photodynamic therapy (PDT) can be a highly complex treatment, with many parameters
influencing treatment efficacy. The extent to which dosimetry is used to monitor and …

Effective treatment delivery in photodynamic therapy (PDT) requires coordination of the light
source, the photosensitizer, and the delivery device appropriate to the target tissue. Lasers …

Photodynamic therapy can be useful for the eradication of malignant cells at sites that are
accessible to light delivery. There are few adverse effects, with many clinical reports …

Photodynamic dose is defined as the area under the curve of sensitizer level plotted as a
function of light dose. This is a photochemical definition of dose. We will show that this …

SUMMARY 1 Photodynamic therapy is an established modality for the treatment of solid
tumours and other accessible lesions. Although the concept and practice of combining light …

Abstract Background and Objective Photodynamic therapy (PDT) based on topical
application of photosensitizers has been under development over the last years. Typical …

When light is diffusely reflected from tissue containing a dye, such as a photosensitizer, with
a known absorption spectrum, the changes in the reflectance spectrum caused by the …
