Which transducer array best produces sector-shaped images due to its curved geometry?

• A. Convex Sequential Array
• B. Linear Phased Array
• C. Linear Sequenced Array
• D. CW Transducers

Answer: (A)

A curved transducer footprint shapes the image. A convex array has a curved emitting surface, so the beams fan out from that curved aperture and create a sector or wedge-shaped field of view. That curved geometry directly produces sector-shaped images, which is why abdominal and some organ scans use convex probes. In contrast, linear arrays have a flat face and typically yield rectangular fields (even with electronic steering), and continuous-wave transducers are used for Doppler and don’t define the B-mode sector shape. So, the convex sequential array best produces sector-shaped images due to its curved geometry.
