Ultrasound Therapy Systems, Hyperthermia
Definition : Ultrasound therapy systems designed to heat solid tumors several degrees Celsius above core temperature, typically from 42 degrees to 45 degrees C (108 degrees to 113 degrees F); these temperatures do not damage normal tissues. These systems consist of a radiofrequency generator, ultrasound transducers, a cooling system, temperature sensors, and a computerized control unit. Ultrasound hyperthermia systems are used to treat solid malignant tumors, frequently in combination with ionizing radiation (thermoradiotherapy) or chemotherapy (thermochemotherapy); they cannot be used for tumors near bone or air-filled cavities such as the lungs.
