Practical S-Sequence aperture coding schemes for volumetric imaging with Top Orthogonal to Bottom Electrode (TOBE) arrays

Recently Top-Orthogonal-to-Bottom Electrode (TOBE) 2D CMUT arrays were introduced. These arrays offered the possibility of 3D imaging without requiring a fully-wired array, however, previously proposed imaging schemes suffered from speed or resolution limitations. Here we propose a new imaging scheme which we call Fast Orthogonal Row-Column Electronic Scanning (FORCES). This new approach takes advantage of the bias-sensitivity of CMUTs to enable high-quality and fast B-scan imaging.
