Abstract: A direct contact scanner uses a fiber acoustic waveguide to convey ultrasound from an ultrasound transducer to a direct contact area. The waveguide extends from a main body of the scanner into an oblong nose, and terminates in a deflector. To minimize thickness of the nose, the waveguide and deflector are rotated about an ultrasound transmission axis of the waveguide, enabling the scanner to be used in a variety of situations where quarters are cramped. A coupling fluid conveys ultrasound between the deflector and a radome, which directly contacts the object to be scanned. Using the waveguide, an ultrasound transducer and supporting electronics may be distanced from the direct contact area and separated from the fluid, thereby insulating the fluid from possible electronic leakage currents and heat.
