Ultrasonic transducer probe

An ultrasonic transducer having a transducer head, for insonifying an organ or part thereof in a human patient from a position within the suprasternal notch thereof, wherein the transducer head is in at least a partially obscured disposition within the notch vis-a-vis the operator thereof during insonification, is comprised of an elongate handle member with a proximal and a distal end, having a non-circular peripheral cross-sectional geometry including at least one longitudinal edge to yield a gripping surface providing the operator with the ability to manipulate the probe via tactile sensing of its position and a transducer head extending from the distal end of, and generally normal to, the handle, wherein the head has a generally arcuate cross-sectional geometry and a generally trapezoidal profile to enhance patient comfort during operator manipulation of the probe.
