An ultrasonic transducer assembly is provided with transducers for both therapeutic and diagnostic ultrasonic radiation. A moveable seal permits adjustment and alignment of the two transducer units in a fluid medium. In addition, there is provided a light beam directed along the axis of the ultrasonic radiation. The transducer assembly is particularly useful for ophthalmic therapy.

Described herein is a device for positioning and fixing an echosignal sensor and sensors of electric signals in an apparatus for taking cardiograms having an echocardiograph and an electrocardiograph. The device has a base with two mutually perpendicular guideways for the movable carriage to travel thereon. The carriage carries a swivel head with a socket for accommodating the echosignal sensor. The swivel head is angularly displaceable in such a way that the centers of rotation of the socket and of the head itself coincide. The sensors of electric signals are fixed stationary on the base.
