Abstract
The surface temperature of tissue adjacent to an ultrasound transducer in an ultrasound imaging probe is determined by a differential measurement technique. A first temperature representative of the temperature of the ultrasound transducer is measured with a first temperature sensor. A second temperature representative of the ambient temperature of the tissue in a region that is thermally isolated from the ultrasound transducer is measured with a second temperature sensor. The surface temperature of the tissue adjacent to the ultrasound transducer is calculated from the first measured temperature and the second measured temperature. The energy transmitted by the ultrasound transducer can be controlled in response to the calculated surface temperature, typically by reducing the transmitted ultrasound energy when the calculated surface temperature exceeds a temperature limit.
