Abstract
A system and method for controlling the heat of an ultrasonic transducer is disclosed. The presently preferred embodiments of the present invention control the temperature of the transducer face by changing the imaging modes of the system. In a preferred embodiment, feedback from temperature sensing elements placed in the transducer is used to determine when to switch from a higher power imaging mode to a lower power imaging mode. In another preferred embodiment, the system switches from a higher power imaging mode to a lower power imaging mode after a predetermined period of time has elapsed. In yet another preferred embodiment, the system switches to a “mixed” imaging mode, where the system cycles rapidly between a higher power imaging mode and a lower power imaging mode, and the resulting data is combined to form a single image.
