<P>PROBLEM TO BE SOLVED: To provide a system and a method for lowering the temperature of an ultrasonic transducer without simply turning off the transducer. <P>SOLUTION: The system and the method for controlling the heat of the ultrasonic transducer is disclosed. The presently preferred embodiments of this 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 is switched from the higher power imaging mode to the lower power imaging mode after a predetermined period of time has elapsed. In yet another preferred embodiment, the system is switched to a "mixed" imaging mode, where the system cycles rapidly between the higher power imaging mode and the lower power imaging mode, and the resulting data is combined to form a single image. <P>COPYRIGHT: (C)2004,JPO |
