An ultrasound assembly adapted to be attached to an endoscope includes a multiconductor electrical connector and a first multiconductor cable connected to the connector. An endoscope attachment element, attached to the multiconductor cable is sized to attach to the distal end of the endoscope and a resiliently deformable neck is connected and extends in a distal manner from the distal end of the first multiconductor cable, and has a distal end. A second multiconductor cable has a proximal end connected to the distal end of the first multiconductor cable. Further, an ultrasound transducer head includes a protective covering, supported by the distal end of the neck, and an ultrasound transducer, inside the protective covering and electrically connected to the distal end of the second multiconductor cable. Finally, a tension member is connected to the ultrasound transducer head and is long enough to extend along the length of the target endoscope.
