Transducer rotation: a useful scanning maneuver in three-dimensional ultrasonic volume imaging.
In ultrasonic volume imaging, the effect of rotating the transducer about the central axis of the imaging plane is equivalent to rotation of the insonified volume. The authors present schematics to depict the action and sonograms in two cases (a hand immersed in water and a 36-week fetus) to demonstrate this phenomenon. This maneuver can be used to "rotate" the imaged structures, which enhances their three-dimensional representation.
