Notice of Removal: Improved left ventricular wall visualization in stress-echocardiography using real-time GPU-based harmonic spatial coherence imaging

Stress echocardiography is an ultrasound imaging technique to assess the functionality of wall segments of the left ventricle (LV). However, image quality is inadequate in up to 30% of patients, requiring the administration of contrast agents. Coherence-based beamforming methods have shown promise in improving image quality by mitigating clutter, a major source of image degradation. In a previous work, we introduced a coherence imaging system with a GPU-based software beamformer capable of real-time cardiac imaging. Here, the system is used in a clinical study to assess endocardial walls using standard clinical techniques and coherence beamforming.
