ABSTRACT:
A noncontacting method and apparatus which uses heat to destroy tumor cells in living tissue. A bidirectionally focused beam of electromagnetic energy, having a pair of electrically and thermally related, spaced focal regions, is positioned so that one of its focal regions embraces a tumor site within living tissue and the other focal region embraces a simulated tumor which is disposed in a liquid medium contained in a tank. Thermal conditions occurring in the focal region embracing the simulated tumor are monitored to reflect thermal conditions occurring within the tumor site. Positioning of the beam is continued until preselected time and temperature conditions are attained which indicate that cell death has occurred within the tumor site.
