The video demonstrates an ultrasound-guided peripheral IV insertion ... risks by preventing the transducer and ultrasound coupling gel from coming into contact with the needle insertion site.

Focused ultrasound (FUS) uses ultrasonic energy ... to ensure that the FUS device functioned consistently; that acoustic coupling, or a gel that allows the signals to transmit from the body ...
