Convex array

Convex (sequential) arrays, also known as curvilinear or curved linear arrays, are similar to linear arrays but with piezoelectric elements arranged along with a curved transducer head. Ultrasound beams are emitted at 90 degrees to the transducer head. This arrangement results in a trapezoidal field of view due to the divergence of the ultrasound beam with increasing depth. This allows for a wider field of view but with decreased line density at depth and reduced lateral resolution
