A real time thermal profile of the target and electric field readings provide feedback to the control. The frequency, amplitude, and relative phase of the EMR can be varied as necessary to create desired hyperthermia heating patterns in the target. The system utilizes controlled constructive interference between EMR emitted by several applicators in order to provide improved heating in the central regions of the target. Several different applicator arrays are suitable for use with the system, and comprise generally cylindrical annuli which emit radiation toward a central axis. | |
