Medical ultrasound images are reconstructed with simplifying assumptions on wave
propagation, with one of the most prominent assumptions being that the imaging medium is …

Tissue harmonic imaging (THI) is a new gray-scale sonographic technique that improves
image clarity. Harmonics form within the insonated tissue as a consequence of nonlinear …

Diagnostic Ultrasound Imaging provides a unified description of the physical principles of
ultrasound imaging, signal processing, systems and measurements. This comprehensive …

A full-wave equation that describes nonlinear propagation in a heterogeneous attenuating
medium is solved numerically with finite differences in the time domain (FDTD). This …

Ultrasonic pulse propagation through the human abdominal wall has been simulated using
a model for two-dimensional propagation through anatomically realistic tissue cross …

The relative importance of the fat and muscle layers of the human abdominal wall in
producing ultrasonic wavefront distortion was assessed by means of direct measurements …

Short-lag spatial coherence (SLSC) imaging is a novel beamforming technique that reduces
acoustic clutter in ultrasound images. A clinical study was conducted to investigate clutter …

A finite-difference time-domain model for ultrasonic pulse propagation through soft tissue
has been extended to incorporate absorption effects as well as longitudinal-wave …

This is the second article in a series of two which report on a matrix approach for ultrasound
imaging in heterogeneous media. This article describes the quantification and correction of …

Wavefront propagation through the abdominal wall was simulated using a finite-difference
time-domain implementation of the linearized wave propagation equations for a lossless …
