    Abstract: A multiplane ultrasound probe, particularly for echocardiographic use, has a phased array transducer and a motor for rotating the transducer in its tip. A liquid film is provided between the acoustic window and the transducer. A spring presses the transducer against the film and the acoustic window. Thus acoustic coupling and a sliding bearing effect is achieved.
