Abstract

An omnidirectional ultrasonic probe, having specific application for connection to the distal end of an esophageal catheter, includes a support member upon which are coaxially mounted a transmitter member, a receiver member, and one or more acoustic reflector members. The acoustic reflector member or members reflect transmissions and receptions of ultrasonic signals along substantially parallel paths. The reflector members also provide omnidirectional reflection. Separate transmitter and receiver members are used in the preferred embodiments to facilitate continuous wave operation.
