Abstract
A thermal therapy of body tissue with electromagnetic energy is controlled by feedback from one or more temperature sensors placed in the vicinity of the tissue to be treated. The temperature sensors are calibrated by comparing stabilized temperature values of the one or more temperature sensors against a normal range of body temperature and adjusting sensed temperature to a value within a normal body temperature range if the actual temperature value of a stabilized temperature sensor is less than the normal body temperature range. The temperature adjustment to the temperature sensor is maintained throughout the thermal therapy which reduces the risk of thermal damage to healthy tissue located near the tissue to be treated.
