<p>Hyperthermia apparatus includes a hyperthermia treatment subsystem (12), and a receiver subsystem (16). The subsystems include, respectively, a power source (30) and radiometer (33) connected to a switch (31) controlled by a central processing unit (CPU) (20) to selectively connect either the power source and the radiometer to complete the subsystems as follows. A power divider (32) having output ports for feeding electromagnetic energy through a plurality of applicator circuits each circuit including a phase shifter (34) connected to the power divider, a power regulating switch (37) connected to the phase shifter, and an applicator (36) connected to the power control switches. The power regulating switches are controlled also by the CPU. Thus, when the CPU connects the power source to the power divider the hyperthermia subsystem is complete for operation in the tissue heating mode; however, when the CPU connects the radiometer, the receiver subsystem is complete. A second embodiment includes a separate radiometer connected to each antenna port.</p> |
