<p>The invention features an acoustic medical device (2) for making Doppler measurements, and imaging within a body fluid conduit using a single-transducer (8). The device has an elongated device body (6), defining a device axis, constructed for positioning a distal end of the device body near a region of interest (15) in the body fluid conduit (14). Disposed within the device body is an ultrasonic beam directing assembly (20) that is constructed to direct a portion of ultrasonic energy from a single transducer (8) in a direction (A-A) for imaging within the body fluid conduit, and to direct another portion of the ultrasonic energy in a direction (B-B) for making Doppler measurements within the body fluid conduit.</p> |
