A _______ image is created with a linear sequential array transducer.

A _______ image is created with a linear sequential array transducer.

• A. Rectangular
• B. Circular
• C. Linear
• D. Spherical

Answer: (A)

The shape of the ultrasound image is determined by the transducer’s geometry. A linear sequential array uses elements lined up in one straight row and beams are scanned across the width to form a grid of scan lines. This arrangement fills a rectangular footprint on the display, so the resulting image appears rectangular. Circular or spherical array designs produce circular or curved-field views, not rectangular ones, which is why a rectangular image is the best fit for a linear sequential array.
