TL;DR: Flexible high sensitivity pressure sensors based on irregular microhump patterns that show great potential in the next generation of smart sensors for robotics, real-time health monitoring, and biomedical applications are proposed and developed.
Journal ArticleDOI
Vector Projectile Imaging: Time-Resolved Dynamic Visualization of Complex Flow Patterns
TL;DR: A new ultrasound-based framework called vector projectile imaging (VPI) that can dynamically render complex flow patterns over an imaging view at millisecond time resolution is presented and suggests that VPI holds promise as a new tool for complex flow analysis.
Journal ArticleDOI
GPU-based beamformer: Fast realization of plane wave compounding and synthetic aperture imaging
TL;DR: A novel beamformer architecture with the real-time parallel processing capacity needed to enable fast realization of PW compounding and SA imaging and can compute compounded 512 × 255 pixel PW and SA images at throughputs of over 4700 fps and 3000 fps, respectively.
Journal ArticleDOI
Medical Ultrasound Imaging: To GPU or Not to GPU?
TL;DR: This article explores the suitability of using GPUs as the primary signal and image processors for future medical ultrasound imaging systems and illustrates the promise of using high-performance GPUs in such systems.

Least-Squares Multi-Angle Doppler Estimators for Plane-Wave Vector Flow Imaging
Billy Y. S. Yiu,Alfred C. H. Yu +1 more
TL;DR: Flow vectors derived from multi-angle Doppler vector estimators were found to be effective in rendering the expected flow paths in both rotating disk and straight-tube imaging scenarios, while the ones derived from the dual-angle estimator yielded flow paths that deviated from the expected course.
