Which term describes a curved linear transducer containing multiple piezoelectric elements?

Explanation:
A curved linear transducer containing multiple piezoelectric elements is called a convex array. The curved arrangement shapes the emitted beam into a fan or sector, giving a wider field of view especially useful at shallow to mid depths. This geometry differentiates it from a flat linear array; while “array” simply means multiple elements, the convex (curvilinear) form is the descriptor for the curved, multi-element transducer. Aperture, apodization, and general array terminology describe other aspects (width of the active elements, weighting to reduce side lobes, etc.) rather than the curved shape itself.
