Ultrasound clutter and noise improvements applied to echocardiographic left atrial appendage visualization

Summary Ultrasonic imaging is the most widely used advanced imaging modality in the United States, and excluding planar radiography, it represents 44% of all imaging studies. Unfortunately, ultrasound images are often subopti- mal, and some echocardiography studies show degradation in up to 98% of patients. This rate of degradation and the freehand nature of clinical ultrasound means that image quality is more dependent on operator skill than other advanced modalities, but even with the most skilled practitioners, ultrasound completely fails in 11-64% of clinical tasks. Our overall goal for this application is to fundamentally decrease ultrasound failure rates. Low-quality ultrasound is…
