摘要： A fully wetted ultrasound scan head (10) for medical applications is described in which the motor (18) and the rotor (12) are enclosed within a sealed housing filled with ultrasound coupling fluid. The invention includes a drive belt (16) to drive the rotor from the motor, rather than a precision drive means. Speed adjustment means, including an encoder disk mounted on the rotor, provide feedback for an electronic speed controller. Accordingly, the speed of the motor can be adjusted as a direct consequence of the actual speed of the rotor.

摘要： A method of manufacturing a phased array ultrasound transducer, and the transducer manufactured by the inventive method are described. In the method, a piezoelectric crystal is soldered to the edges of a pair of double sided printed circuit boards, each of which has traces on either side. Then, a backing material is poured to secure the crystal and boards, and a saw is used to define the elements of the transducer.
