An integrated modal approach to surface and volume scattering in ocean acoustic waveguides
… and rough elastic halfspaces is modeled, and statistics of the acoustic field are calculated. Numerical results show the modal formulation agrees well with Kuperman and Schmidt's model, while reducing computation times by several orders of magnitude for the scenarios considered. Next, a …

Peripheral perfusion imaging modeling
Effective clutter and noise filtering is critical for contrast-free ultrasonic per- fusion imaging. Novel pulsed-Doppler methods for perfusion imaging are val- idated using dialysis cartridges as perfusion phantoms. Techniques are exam- ined quantitatively at 5 and 12.5 MHz using phantoms with …
