摘要： An ultrasonic imaging system and method for imaging human or animal tissue having a surface and including a probe comprising a platen for defining the surface in a manner supporting the human or animal tissue for imaging the same, a transducer positioned closely adjacent the supporting platen for providing an output ultrasonic beam directed on the surface so that the size of the beam at its focal point is as small as possible to maximize the resolution of the system an electrically operated motor for moving the transducer in a manner such that the ultrasonic beam is directed in a path along the surface. A fluid-tight housing extends from the tissue-supporting surface and has an interior region containing the transducer and motor which region is filled by an electrically non-conductive fluid having an acoustic impedance substantially equal to that of water and having a viscosity sufficiently low so as not to impede the movement of the transducer. The housing is provided with a bellows for accommodating thermal expansion and contraction of the fluid. In one aspect of the invention, the motor provides oscillatory output motion and the output shaft is coupled to the transducer so that in response to oscillation of the shaft the output ultrasonic beam is directed in the path along the surface. An encoder is mounted on the shaft between the motor and coupling to minimize any distortion in the information provided by the encoder. The coupling is in the form of an elongated arm having a structure of sufficient rigidity so as not to bend or flex during oscillation of the motor shaft while having minimal drag as the arm moves through the fluid.
