The primary purpose of the ultrasound transducer is to convert electrical energy into sound waves and vice versa. This dual function is essential for ultrasound imaging; when the device emits electrical signals, these are transformed into sound waves that travel through the body. After interacting with tissues, some of these sound waves are reflected back to the transducer, allowing it to convert them back into electrical signals. These electrical signals are then processed to create images of the internal structures.

The ability of the transducer to perform both functions is what makes it a critical component in ultrasound technology, enabling the visualization of anatomy dynamics in real-time. This conversion process is foundational to how ultrasound imaging works, thus establishing the transducer's pivotal role within the ultrasound system.
