Patent ID: 8251929

Claim:
An integrated ultrasound therapy transducer assembly comprising: an enclosure; a piezoelectric transducer to generate therapy ultrasound; a support to support the piezoelectric transducer; and a power amplifying module to drive the piezoelectric transducer, wherein the power amplifying module and the piezoelectric transducer are installed within the enclosure, and wherein a passage for circulating a cooling fluid is formed between a portion of a radiating surface of the power amplifying module and the piezoelectric transducer such that the cooling fluid flowing in the passage simultaneously cools the piezoelectric transducer and the power amplifying module, wherein said power amplifying module is installed at a back side of the piezoelectric transducer and located at an opposite side of an acoustic emitting surface of the piezoelectric transducer, wherein the power amplifying module is directly connected to a back wall and side walls of the enclosure, and wherein the enclosure is used as a radiating board of the power amplifying module.
