When one element in a linear sequential array transducer is damaged, which lines are affected?

When one element in a linear sequential array transducer is damaged, which lines are affected?

• A. The whole image
• B. Only adjacent lines
• C. The scan lines that would have been created by the defective crystal
• D. None of the above

Answer: (C)

In a linear sequential array, each element contributes to a specific scan line as the array fires element by element. If one element is damaged, that element can’t emit or receive properly, so the scan line that would have been formed by that particular crystal is corrupted or missing. The other elements continue to produce their own lines, so the rest of the image remains intact. The visual effect is a vertical band where that element’s line would appear, rather than a blanket problem across the entire image or just the lines next to it. That’s why the affected lines are precisely the ones that would have been created by the defective crystal.
