Efficient Spatial Coherence Estimation for Improved Endocardial Border Visualization in Real-Time
Coronary heart disease contributed to approximately one in four deaths in the United States in 2014, and is caused by a restriction of blood flow to myocardial tissue. Stress echocardiography is a clinical technique used ...
Ultrasound Beamforming Methods for Large Coherent Apertures
This dissertation investigates the use of large coherent ultrasound apertures to improve diagnostic image quality for deep clinical targets. The current generation of ultrasound scanners restrict aperture size and geometry ...
Beamforming of Ultrasound Signals from 1-D and 2-D Arrays under Challenging Imaging Conditions
Beamforming of ultrasound signals in the presence of clutter, or partial aperture blockage by an acoustic obstacle can lead to reduced visibility of the structures of interest and diminished diagnostic value of the resulting ...
