In a linear sequential array transducer, the sound beams are _______ to each other.

In a linear sequential array transducer, the sound beams are _______ to each other.

• A. Perpendicular
• B. Parallel
• C. Diverging
• D. Converging

Answer: (B)

Beams are parallel to each other. In a linear sequential array, the elements sit along a straight line and emit beams in sequence with essentially the same steering angle. That means the scan lines run side by side without bending toward or away from a focal point, producing parallel beams and a rectangular field of view. Diverging or converging would require different array geometries or focusing methods, and perpendicular would imply beams crossing at right angles—neither describes a linear sequential array.
