What role does the transducer play in an ultrasound procedure?

The transducer in an ultrasound procedure serves a crucial function by transmitting and receiving sound waves. This device converts electrical energy into acoustic energy, which produces sound waves that are sent into the body. These sound waves then bounce off of internal structures and return to the transducer, where they are converted back into electrical signals. These electrical signals are then processed to create an image of the internal structures, such as organs or tissues.

Without the transducer's ability to both send out and capture these sound waves, imaging would not be possible. This dual capability is essential for the ultrasound to function effectively, making it the central component in the examination process. The transducer and its operation are fundamental to the production of diagnostic ultrasound images.
