Method for Controlling Photodynamic Therapy Irradiation and Related Instrumentation
In a first embodiment, there is no monitoring, and instead light is delivered according to a predetermined "recipe." In a second embodiment, the instrumentation provides a means for making the reflectance measurements during therapy without requiring the brief interruption. This device may therefore allow more accurate measurement of treatment-induced changes to the reflectance measurement. In a third embodiment, an adjustable aperture is used to constrict the area of a treatment beam.
