Abstract

A microwave body heating system uses one or more focused beams of microwave energy. A fan beam or transversely scanned beam is directed to a narrow transverse section of a subject'"'"'s body. The transversely scanned or fan beam is moved longitudinally down the body in a controlled sequential incremental manner. Scanning times, patterns and radiated power levels are controlled in experimentally predetermined or monitored formats to achieve desired levels of heating of an entire body or localized area. Microwave frequency energy is provided by one or more magnetron type devices in a variably positionable microwave power assembly which is longitudinally scanned under control of a motor device.

Claims

1. A system, to heat body portions using controlled microwave energy, comprising:

a support unit arranged to support a subject body portion;

a microwave power assembly comprising a plurality of microwave power supply devices, each of said microwave power supply devices being capable of irradiating a focused directional beam of microwave frequency energy at a controllable power level, said assembly being variably positionable relative to said support unit;

a position adjustment element arranged to electromechanically position said microwave power assembly; and

a central processor unit coupled to said position adjustment element, arranged to control positioning of said microwave power assembly and arranged to control at least one of the power level, the beam focus and the beam direction of each of said beams of microwave frequency energy irradiated by said microwave power supply devices.

2. A system as in claim 1, wherein said support unit is a table structure suitable for support of a human subject.

3. The system of claim 2, wherein said position adjustment element is arranged to electromechanically position said microwave power assembly at any location along the entire length of a human subject.

4. A system as in claim 1, wherein said microwave power supply devices are magnetron devices.

5. A system as in claim 1, wherein at least one of said microwave power supply devices is positioned in at least one of the locations relative to said support unit, above the support unit, below a body portion support surface of said support unit, to the left of said support unit, and to the right of said support unit.

6. A system as in claim 1, wherein said position adjustment element comprises an electric motor arranged to electromechanically position said microwave power assembly along at least one structural rail extending longitudinally.

7. A system as in claim 1, wherein said central processor unit comprises a computer system with associated memory.

8. A system as in claim 1, additionally comprising radiation sensing means responsive to the power level of said radiated beams of microwave frequency energy.

9. The system of claim 1, wherein said microwave power assembly includes at least one of said microwave power supply devices positioned in at least one of the locations relative to said support unit to the left of said support unit and to the right of said support unit.

10. The system of claim 1, wherein the subject body portion is a head.

11. The system of claim 1, wherein said microwave power assembly comprises at least three of said microwave power supply devices, at least one of said devices positioned in at least one of the locations relative to the support unit to the left of said support unit and to the right of said support unit.

12. The system of claim 1, wherein at least one of said focused directional beams of microwave frequency energy is capable of being laterally scanned.

13. A method, to heat body portions using controlled microwave energy, comprising the steps of:

(a) positioning a subject body portion on a support unit;

(b) irradiating towards said subject body portion a plurality of focused directional beams of microwave frequency energy, each at a controllable power level, using a variably positionable microwave power assembly comprising a plurality of microwave power supply devices each being capable of irradiating a focused directional beam of microwave frequency energy at a controllable power level;

(c) electromechanically positioning said microwave power assembly relative to said support unit; and

(d) controlling at least one of the power level, the beam focus and the beam direction of said beams of microwave frequency energy irradiated by said microwave power supply devices.

14. A method as in claim 13, wherein said step (c) positioning is coordinated with said step (d) controlling in order to provide a predetermined level of heating of said subject body portion.

15. A method as in claim 13, wherein step (c) comprises electromechanically moving said microwave power assembly a predetermined longitudinal distance at a predetermined rate.
