We have developed a new, fast, and simple 3-D imaging approach referred to as Simultaneous Azimuth and Fresnel Elevation (SAFE) compounding using a bias-sensitive crossed-electrode array. The principle behind this technique is to perform conventional

Three-dimensional ultrasound imaging presents the technical challenges of addressing large numbers of elements in 2-D array transducers. Top-orthogonal-to-bottom electrode (TOBE) 2-D transducer arrays can simplify addressing but typical imaging metho

We introduce novel bias-sensitive piezoelectric transducer (relaxor) arrays for 3D photoacoustic imaging. A 64×64 element relaxor array using a crossed electrode or Top-Orthogonal to Bottom-Electrode (TOBE) wiring configuration is used to receive ph

Capacitive micromachined ultrasonic transducers (CMUTs) promise many advantages over traditional piezoelectric transducers such as the potential to construct large, cost-effective 2-D arrays. To avoid wiring congestion issues associated with fully wi

Recently, top-orthogonal-to-bottom electrode 2-D arrays were introduced as a practical design for 3-D ultrasound imaging without requiring the wiring of a 2-D grid of elements. However, previously proposed imaging schemes suffered from speed or image

A novel 3D photoacoustic imaging technique is experimentally demonstrated using a 64×64 element bias-sensitive crossed-electrode relaxor array. This technique allows for large 2D arrays to receive across all elements while using minimal channel coun

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 resolutio

This paper demonstrates a clockless stochastic low-density parity-check (LDPC) decoder implemented on a Field-Programmable Gate Array (FPGA). Stochastic computing reduces the wiring complexity necessary for decoding by replacing operations such as mu
