  • Patent number: 5231997
    Abstract: A heating apparatus for hyperthermia utilizes electromagnetic waves for locally heating cancerous cells within a living body. Electromagnetic waves output from a single electromagnetic wave generating means are branched into a plurality of branched electromagnetic waves, which are respectively employed to conduct hyperthermia treatments for a plurality of patients. The whole of the hyperthermia system is controlled in a concentrated fashion from a single section by means of time-division multiplexing. It is therefore possible for a plurality of patients to be subjected to hyperthermia treatment at the same time and in parallel with each other, even when the conditions of these patients differ from one another. Further, it is advantageously possible to simplify the arrangement of the system as a whole and stabilize the control of the system.

  • Patent number: 4747416
    Abstract: A heating apparatus for hyperthermia utilizes electromagnetic waves for locally heating cancerous cells within a living body. When it is necessary for a plurality of patients to be subjected to hyperthermia treatment at the same time and in parallel with each other, the control of a plurality of electromagnetic wave outputs and the control of cooling of the surface of a heated region are effected by a centralized control which employs time-division multiplexing. Thus, it is advantageously possible to efficiently carry out a hyperthermia treatment which is fitting for the condition of each of a plurality of patients.

  • Patent number: 4690156
    Abstract: Coolant liquid is caused to flow through a lens section of an applicator to control the heating of the applicator due to a loss in propagation of the electromagnetic waves in the applicator. Furthermore, in this applicator, device for decreasing the internal loss, device for improving a lens effect to efficiently heat a predetermined portion in a living body, and the like are provided, respectively, as necessary.
