Which transducer is typically used for broad-depth abdominal imaging?

• A. Convex array
• B. Mechanical sector
• C. Linear array
• D. Phased array

Answer: (A)

In abdominal imaging across a wide range of depths, you need both penetration and a broad viewing area. The curved footprint of a convex array provides a wide imaging sector and, as a lower-frequency option, can penetrate deeper tissues effectively. That combination makes it the typical choice for broad-depth abdominal scans. The other transducers have different strengths: a mechanical sector offers a fixed, narrow sector and less versatility for large, deep areas; a linear array delivers high-resolution images but along a narrower, more superficial field; a phased array is compact and steered for small, focused regions like the heart, not for broad abdominal surveys.
