The linear sequential array has a ______ footprint and creates ______ images.

The linear sequential array has a ______ footprint and creates ______ images.

• A. Large acoustic footprint; Rectangular images
• B. Small acoustic footprint; Circular images
• C. Large acoustic footprint; Circular images
• D. Small acoustic footprint; Rectangular images

Answer: (A)

A linear sequential array uses a wide, flat, rectangular aperture and fires its elements one after another across that width. That wide physical footprint means the probe covers a large contact area on the patient. As the system builds the image, it emits parallel scan lines across the width, producing a field that is rectangular in shape on the display. So this design yields a large acoustic (physical) footprint and rectangular images.
