1. An apparatus for measuring the volume of fluid in a human or animal body cavity using a non-invasive, ultrasound echo technique, comprising:

  • a transducer assembly including a plurality of ultrasound transducers mounted thereon for transmitting and receiving a plurality of ultrasound signals into the body cavity at plural angles of incidence and/or from plural spatial locations;

    means for activating the transducers to produce transmitted ultrasound signals;

    means for detecting body cavity wall echoes from received ultrasound signals;

    means for determining, from said received signals, a body cavity height H and depth D;

    means for determining a specific measurement configuration corresponding to the body cavity filling degree from the ultrasound signals that intercept the fluid filled body cavity to thereby select an appropriate predetermined correction factor K corresponding to that specific measurement configuration, for optimal calculation of the volume; and

    means for calculating the fluid volume according to the formula H×



    K.
