Which term is commonly used to describe bowed or curved transducers in clinical practice?

• A. Concave
• B. Flat
• C. Spherical
• D. Convex

Answer: (D)

Transducer shape determines the field of view and image geometry. Bowed or curved transducers have an outward curve on the patient-facing surface, which is described as convex. That outward curvature steers the ultrasound beam into a wider, sector-shaped field, making the convex (curved array) transducer the standard choice for abdominal imaging and other deeper areas. The term concave is older or less common terminology for a curved surface, flat describes a noncurved, linear surface, and spherical isn’t used to name this transducer type in typical practice. So, convex is the commonly used descriptor for bowed or curved transducers.
