Which statement is true about the scan plane in a mechanical transducer?

• A. Electronic Steering
• B. Acoustic Lens Adjustment
• C. Phased Adjustment
• D. Mechanical Steering

Answer: (D)

The scan plane in a mechanical transducer is created by mechanical steering: the beam is physically moved by a motor or rotating element that sweeps the crystal or reflector through different angles, producing the scanned plane across the image. This is different from electronic steering, where multiple elements are phase-delayed to steer the beam without moving the transducer; lens adjustments modify focus or beam shape but don’t sweep the plane, and electronic (phased) steering uses timing delays rather than mechanical motion. So mechanical steering is the way the scan plane is controlled in a mechanical transducer.
