Proton Beam Therapy (May 1999)
May 1999 pages 3-5 Coding Communication Proton Beam Therapy Although the term proton beam therapy may sound very futuristic, the fact is, this radiation treatment modality has actually been used since 1955. The advantages of using this treatment include the delivery of energy near the end of range in the tumor and delivering smaller dose to the intervening normal tissues and organs. With selection of appropriate incident energy, the protons stop abruptly, distal to the target and deposit no dose beyond that boundary. Due to their physical properties, proton beams can deliver higher radiation doses to tumors than can...
