Which QA test would indicate a problem if the beam profile is uneven or distorted?

Explanation:
Directly assessing how the ultrasound energy is distributed in space reveals beam quality. If the beam profile is uneven or distorted, a beam-profile measurement will show areas of low and high intensity, off-axis energy, or a broadened focal spot. This pattern points to issues in how the beam is formed—such as problems with transducer elements, backing, matching layers, or alignment—because that test specifically maps the spatial distribution of the emitted field. Other QA tests look at electrical characteristics, overall transmitted energy, or physical condition, and they don’t directly reveal irregularities in the beam’s shape.
