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 ...
Functional and Molecular Imaging Using Nanoparticle Contrast Agents for Dual-Energy Computed Tomography
X-ray computed tomography (CT) is one of the most useful diagnostic tools for clinicians, with widespread availability, fast scan times, and low cost. CT imaging can reveal a patient’s anatomy in exquisite detail and is ...
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 ...
