Exposing the patient with X or Gamma rays at a distance from the patient is called teletheraphy. While exposing the radiation to the tumor volume it is mandatory to shield normal tissues and critical organs from radiation exposures. There are standard shape radiations shields are available or supplied by the manufacturer. But there are many situations where standard shape radiation shields cannot be used. Using this Styrofoam Cutter individual irregular shaped radiation shields can be made. This is a mechanical system has an X ray film holder and hanging styles mechanism along with a heating wire cut Styrofoam. This mechanism simulates Teletheraphy machine beam divergence so that the regular beam shape can be accurately prepared.
