Abstract
The present application discloses a method of estimating a surface temperature of an ultrasound probe having a plurality of transducer elements and a surface, involving: a) establishing a temperature rise function of the surface of the ultrasound probe due to a single active transducer element; b) selecting one of the transducer elements; c) applying a single transmission pulse signal to the selected transducer element such that the selected transducer element operates once; d) measuring a temperature rise of the surface of the ultrasound probe at predetermined positions on the surface thereof; e) completing the temperature rise function based on the measured temperature rise; and f) estimating a temperature rise of the surface of the ultrasound probe based on the temperature rise function.
