During color Doppler exams with a linear array transducer, the resulting image is described as which shape?

Explanation:
The image shape reflects the transducer geometry. A linear array uses a straight line of elements and beamforms to create parallel scan lines across a flat, rectangular window. That produces a rectangular field of view on the screen, which is where the color Doppler information is displayed. Curved or convex arrays create sector- or curved-shaped windows, and circular or other non-linear geometries would yield different shapes, not a rectangle. So, color Doppler with a linear array appears rectangular.
