Hyperthermia treatment system
WO 2004083797 A3
Abstract
Systems and methods are disclosed to control the temperature of an RF hyperthermia system with minimum overshoot and to improve safety by, among other things detecting a defective temperature sensor. Temperature overshoot may be minimized by compensating for the short-term temperature difference between the area being treated and the applicator delivering the RF energy. The RF energy may heat the tissue and then the tissue may transfer heat to the applicator sensor. The system may also adapt to various applicator sizes and shapes by modifying control loop coefficients based on initial probe response. The system may perform a plurality of test to determine proper operation and in response to a failure of these tests, the system may be locked in a “disable and return to factory” mode.
