Claim 5:
6. A method of photodynamically treating a patient, comprising:
applying 5-aminolevulinic acid (ALA) to the skin of the patient to treat actinic keratosis on the extremities or torso of the patient;
irradiating, with visible light, the skin of the patient with a plurality of light sources, each of the plurality of light sources being mounted to a panel of a five-panel illuminator, the five-panel illuminator being configured such that heat is emittable from at least a portion of one of the panels of the five-panel illuminator;
causing air blown from at least one variable-speed fan coupled to one or more of the panels to be directed toward the skin of the patient, and controlling, via a controller, the at least one variable speed fan,
sensing, by a sensor in communication with the controller, a configuration of the illuminator, the configuration of the illuminator corresponding to an orientation of the panels of the five-panel illuminator, and
comparing, by the controller, an existing intensity of the light from the plurality of light sources to an intensity associated with the configuration of the illuminator and determining whether to adjust the intensity of the light sources based on the comparison.
