Abstract
Abstract An apparatus and method are provided for the selective, locally defined heating of an object, particularly a human body to destroy malignant cells of the body. A ring has a plurality of high frequency antennas or the like mounted on the inner surface thereof, capable of focusing together at a common volume. The transmitters may be mounted for limited pivotal movement, and for radial movement, with respect to the ring to provide flexibility in focusing. The ring is preferably disposed generally vertically, and is mounted so that it is rotatable about its center, and pivotal about two perpendicular axes disposed in the plane of the ring, and is mounted for reciprocal movement in a dimension perpendicular to the plane of the ring. A human body is disposed within the ring and energy is supplied to the transmitters to focus on the malignant cells of the human body, and destroy them. Various structures for enhancing the focusing effect may be provided.

Total Claims: 17
Claim 1
Independent Claim
149 words
Apparatus for the selective, locally defined heating of an object, comprising: a ring; a plurality of high-frequency radiation-emitting transmitters for heating an object upon which the radiation therefrom is directed; means for mounting said transmitters to said ring so that radiation beams emitted by said transmitters intersect each other generally within a common volume generally encompassed by said ring; a radially-extending electromagnetic coil surrounding at least one of said transmitters and comprising means for facilitating focusing of the radiation emitted by said at least one said transmitter; means for mounting said ring so that it is pivotal about two perpendicular axes and is reciprocal along a dimension perpendicular to a plane containing said ring; a plurality of ultrasonic generators; means for mounting said ultrasonic generators on an inner-surface of said ring, each adjacent a transmitter; and control means, responsive to signals from said ultrasonic generators, for positioning said ring.
Claim 2
Dependent Claim
149 words
Apparatus for the selective, locally defined heating of an object, comprising: a ring; a plurality of high-frequency radiation-emitting transmitters for heating an object upon which the radiation therefrom is directed; means for mounting said transmitters to said ring so that radiation beams emitted by said transmitters intersect each other generally within a common volume generally encompassed by said ring; a radially-extending electromagnetic coil surrounding at least one of said transmitters and comprising means for facilitating focusing of the radiation emitted by said at least one said transmitter; means for mounting said ring so that it is pivotal about two perpendicular axes and is reciprocal along a dimension perpendicular to a plane containing said ring; a plurality of ultrasonic generators; means for mounting said ultrasonic generators on an inner-surface of said ring, each adjacent a transmitter; and control means, responsive to signals from said ultrasonic generators, for positioning said ring.
