Abstract

A multi-mode scanner head employing split (semicircular transducers) is described. In some modes such as simultaneous B-scan and M-scan each transducer moves independent of the other. For continuous Doppler mode the transducers move together. The relatively small, hand-held scanner head is particularly useful for cardiac examinations.
