INTERIOR ENERGY-ACTIVATION OF PHOTO-REACTIVE SPECIES INSIDE A MEDIUM OR BODY USING AN X-RAY SOURCE EMITTING LOW ENERGY X-RAYS AS INITIATION ENERGY SOURCE

摘要

A system and method for light stimulation within a medium. The system has a reduced-voltage x-ray source configured to generate x-rays from a peak applied cathode voltage at or below 200 kVp, and a plurality of energy-converting particles in the medium which, upon radiation from the x-ray source, radiate at a first lower energy than the x-ray source to interact witht least one photoactivatable agent in the medium. The method introduces the plurality of energy-converting particles into the medium, radiates the energy-converting particles in the medium with x-rays generated from a peak applied cathode voltage at or below 200 kVp; and emits a lower energy than the x-ray source to interact with the medium or with at least one photoactivatable agent in the medium.
