ABSTRACT:
The invention provides a microwave heating method and apparatus for evenly heating an object, such as a person's body. The methods and apparatus involve use of microwave source (or sources) that outputs multiple microwaves that are non-correlated with each other in phase; an array of antennas that radiate substantially plane microwaves to form a pseudo uniform microwave electromagnetic field, where the microwaves are not phase-correlated, in order to eliminate non-uniform heating caused by interference. Each of the antenna array consists of multiple antenna units, each antenna unit consists of at least one microwave radiator and at least one converter that converts the spherical microwave to plane microwave. A computer based control system and a temperature monitoring subsystem can be used to adjust the output of each antenna, in order to enhance the uniform heating effect. The apparatus and method can be used to perform whole-body hyperthermia or regional hyperthermia.
