During reception the reflected sound pulse is converted into electricity.

During reception the reflected sound pulse is converted into electricity.

• A. Transmission
• B. Echoing
• C. Propagation
• D. Reception

Answer: (D)

During reception, the ultrasound transducer uses the piezoelectric effect to convert the returning acoustic echoes into electrical signals. When the reflected sound pulse arrives, the mechanical energy of the echoes causes the crystal to generate a small voltage, which the system then processes to form an image. This is the reverse of transmission, where electrical energy is turned into sound energy. Propagation describes the movement of the wave through tissue, and echoing refers to the reflections themselves rather than the energy conversion.
