07 Mar 1988TL;DR: A multileaf collimator is formed of a multiplicity of heavy metal bar leaves driven relative to frames which are driven by electric motors and flexible cables in order to shield critical organs not invaded by the tumor as mentioned in this paper.
Abstract: In a radiation therapy machine it is desirable to produce irregular radiation field shapes in order to shield critical organs not invaded by the tumor. A multileaf collimator is formed of a multiplicity of heavy metal bar leaves driven relative to frames which are driven relative to jaws of a rectangular field collimator by electric motors and flexible cables.

22 Aug 1983TL;DR: In this article, a direct contact microwave hyperthermia applicator includes a plurality of rectangular waveguide sections each having a radiating aperture, mounted with their long sides abutting.
Abstract: A direct contact microwave hyperthermia applicator includes a plurality of rectangular waveguide sections each having a radiating aperture. The waveguide sections are mounted with their long sides abutting. A pair of shutter elements for individually varying the radiating aperture is associated with each of the waveguide sections. The shutters can be adjusted to form a desired composite aperture which produces a radiation pattern adapted for efficient hyperthermia treatment of a tumor having a prescribed size, shape and location. Microwave power supplied to the radiating elements can be varied in phase and power level to further control the radiation pattern.
