Abstract
The present invention provides a plurality of permanent magnets to enhance radiation dose delivery of a high energy particle beam. The direction of the magnetic field from the permanent magnets may be changed by moving the permanent magnets.
Claims43
A radiation treatment system comprising:
- a beam source that generates a beam of high energy particles along a beam path directed toward a body;
- and
- a permanent magnet assembly that comprises at least one permanent magnet that generates a magnetic field that causes an increase in the ratio of radiation dose delivered to a target area of the body compared to surrounding regions or to other regions of the body along the beam path.
A method of enhancing target radiation dose in medical treatments, the method comprising:
- directing a high energy particle beam at a body along a beam path;
- and
- orienting a permanent magnet assembly that comprises at least one permanent magnet adjacent a target tissue to create a magnetic field component in the body, wherein the at least one permanent magnet enhances the ratio of radiation dose in a target area of the body, compared to surrounding regions or in other regions of the beam along the beam path.
A radiation treatment system comprising:
- means for generating a beam of high energy particles along a beam path directed toward a body;
- and
- permanent magnet means for generating a magnetic field that causes a dose enhancement in a desired target area of the body, compared to surrounding regions or in other regions of the beam along the beam path.
