Multiple Choice

When the spike line is straight an ______ sound beam is created.

Explanation:
A straight spike line means the beam isn’t being focused; the wavefront remains essentially planar and energy isn’t converging to a focal point. In ultrasound, focusing uses delays across the transducer to bend the wavefront toward a specific depth. When those delays don’t create curvature, the beam stays broad and unfocused, which is what a straight spike line represents. If the line showed curvature—converging toward a point—that would indicate a focused beam.
