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.
