Definitions

  • This invention relates in a general way to radiations capable of penetrating matter. More precisely, it has for its object to provide a method for obtaining a combination of radiations of different kinds capable of penetrating matter, and more particularly of penetrating intimately into living organic tissues and producing certain effect-s therein and most not-ably in human tissues for therapeutic purposes, without destroying therein such essential elements as the enzymes for instance.
  • electrically charged particles are emitted into a cavity, and onto this emission is superimposed a centimetric electromagnetic radiation the wavelength of which preferably lies between 3 cm. and 80 cm., and the resulting radiation issuing from said cavity is directed onto the target to be irradiated.
  • the penetration and particularly the curative effects are very markedly improved when the frequency of the electromagnetic radiation is determined according to the organ or tissue to be penetrated or treated.
  • a wavelength of 14 cm. is suitable for the liver and a wavelength of 19.5 cm. for the spleen.
  • the charged particles radiated are preferably accelerated in a particle accelerator in order to increase the penetration force.
  • the resulting radiation is preferably applied to and directed at the target, namely at the tissue to be penetrated, by means of a tube which is the seat of accelerating and directing magnetic fields and electrical fields, said radiation being with advantage directed and/or reflected by a rotary deflecting device placed within the tube.
