Which shape is commonly associated with the imaging field of phased array transducers?

Explanation:
Phased array transducers steer and focus the beam electronically across a small footprint, sending beams at different angles from adjacent elements. This causes the interrogated region to fan out like a wedge, so the imaging field appears sector-shaped on the display. The sector shape reflects the fan-beam geometry created by electronic steering, unlike the rectangular field typical of linear arrays or other shapes seen with different transducer geometries.
