ABSTRACT:
In a method of operating a photochemotherapy chamber for the irradiation of a patient with long wave ultraviolet light, a prescribed dosage is first selected. The prescribed dosage is then automatically converted into the time duration that an ultraviolet source should be energized to deliver said dosage by monitoring the line voltage and the total hours of operation of the ultraviolet source and adjusting said time duration accordingly.
