Endoscopic probe in particular suitable for use as a TEE-probe, comprising a flexible tube having at one end a probe head which is provided with ultrasonic transducer means of the phased array type with a transducer made up of 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 in which 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, which 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 means of drive means cooperating with the transducer housing, and in which by means of at least one flexible printed circuit board the elongated transducer elements are connected to cables extending through the flexible tube and in which the at least one flexible printed circuit board extends through an opening into the transducer housing, is present in the transducer housing in a loop shape and ends at at least a number of connecting electrodes of transducer elements. |
