Abstract: An endoscopic probe suitable for use as a TEE-probe, comprising a flexible tube having at one end a probe head which is provided with a phased array type ultrasonic transducer comprising a number of elongated transducer elements which elements can be individually electrically controlled by means of cables connected to the individual elements and extending through the flexible tube. The transducer is fitted in an essentially cylindrical transducer housing which is mounted in the probe head with its longitudinal axis extending perpendicularly to the longitudinal axis of the probe head. The transducer housing is fitted rotatable in the probe head in such a way that the transducer is rotatable in the plane of the array by a driver cooperating with the transducer housing. By means of at least on flexible printed circuit board the elongated transducer elements are connected to cables extending through the flexible tube.

Abstract: An endoscopic probe suitable for use as a TEE-probe, comprising a flexible tube having at one end a probe head which is provided with a phased array ultrasonic transducer with a number of elongated transducer elements which can be individually electrically controlled by cables connected to the individual elements and extending through a flexible tube in which the transducer is mounted in a cylindrical transducer housing, which is in a cavity in the probe head and is rotatable about a longitudinal axis extending at right angles to the longitudinal axis of the probe head, by means of a drive means interacting with the transducer housing while the elongated transducer elements are connected by flexible conductors to the cables extending through the flexible tube and in which a convex acoustic lens is mounted on the transducer and the peripheral edge of the lens interacts in a sealing manner with the edge of the cavity in the probe head and can rotate together with the transducer relative to the probe head.
