Convex array

Last revised by Dr Bahman Rasuli on 18 Dec 2020

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
