Abstract

Light for photodynamic therapy is applied by light emitting particles (Figs. 1, 2, and 5) which are inserted into the body of the subject and removed therefrom. The particles may be conveyed by a flowing fluid. The particles may incorporate a luminescent material (22) powered by a radioisotope (20); a long lived phosphorescent material energized while the particles are outside of the body, a chemiluminescent material or electrically actuated light emitting elements (88) such as light emitting diodes.
