A) Linear curved array ultrasonic transducer on the end of an ultrasonic puncture bronchoscope. Used to perform convex probe endobronchial ultrasound. B) The balloon sheath that surrounds the ultrasonic transducer is inflated with water. A 22-gauge needle used for real-time transbronchial fine needle aspiration extends from the bronchoscope.
