Abstract
Invasive hyperthermia apparatus includes an electromagnetic energy radiation source, and a plurality of applicators. Each applicator is adapted for insertion into body tissue and radiating electromagnetic energy therein. Interconnected between the applicators and the radiation source are a power splitter and a plurality of line stretchers for providing the applicator with electromagnetic energy in a preselected frequency - phase power relationship. The applicators, power splitter and line stretchers are operative for causing constructive interference between emitted electromagnetic radiation when the applicators are inserted into body tissue in a preselected spaced apart relationship.
Claims11
Electromagnetic hyperthermia apparatus for heating local regions within body tissue comprising:
- (a) a source of electromagnetic radiation;
- (b) a plurality of electromagnetic energy radiating applicators, wherein said applicators are inserted into the body tissue in a preselected pattern, and further wherein said applicators are substantially parallel;
- and
- (c) means interconnected between the radiation source and each of said applicators for continuously providing each said applicator with electromagnetic energy having the same frequency and preselected relative phase and power relationships, wherein the radiation emitted by said applicators undergoes constructive interference in the local region to be heated.
Electromagnetic hyperthermia apparatus for heating local regions within body tissue, comprising:
- a source of electromagnetic radiation;
- a plurality of individual electromagnetic energy radiators suitable for substantially parallel insertion into the body tissue so as to define points equally spaced on the circumference of a circle;
- a power splitter coupled to said source;
- and
- a plurality of line stretchers coupled between said power splitter and said applicators, wherein the relative phase of energy supplied to said applicators is controlled by said line stretchers.
A method for heating local regions within body tissue with electromagnetic radiation, comprising the steps of:
- (a) inserting a plurality of electromagnetic energy radiating applicators into the body tissue in a substantially parallel, spaced apart relationship;
- and
- (b) simultaneously providing all of the applicators with electromagnetic energy having aligned fields, the same frequency, and preselected relative phase and power relationships.
