Notice of Removal: Swept synthetic study of large aperture imaging through ex vivo human abdominal wall

Lateral resolution and therefore image quality in ultrasound is tied to aperture size. While this relationship is understood in ideal imaging conditions, the utility of a large aperture in the presence of clutter is unknown. This problem is particularly relevant to abdominal imaging where thick tissue layers and deep targets create a challenging imaging environment. Previous studies have focused on the main lobe width of the beam and were limited by the size of commercially available transducers. Enabled by a synthetic aperture technique to form large coherent apertures, we have performed a more comprehensive study of image quality using excised human abdominal walls in a controlled imaging setting.
