Prepared by Albert I. H. Chen and Manu Pallapa, PhD candidates under the supervision of Dr. John Yeow, Department of Systems Design Engineering, Advanced Micro/Nano Devices Lab, University of Waterloo, in co-operation with CMC Microsystems.
This application note describes the architecture of a MEMS-based ultrasound imaging system with capacitive micromachined transducers. The development platform for the system is National Instrument (NI) LabVIEW with supporting hardware—a PXI chassis, a FlexRIO field programmable gate array (FPGA) module (NI 7954), and a FlexRIO digitizer adapter (NI 5752). The output of the system results in an ultrasonic B-Scan (cross-sectional tomography) in the elevation direction, while the sweeping is done in the azimuth direction, such that a pyramidal volumetric scan is made in a near real-time manner.
The downloadable items include the document and a design file.
