Atrial fibrillation is one of the most common arrhythmia, affecting over 2.2 million Americans. A prevailing modality for treating paroxysmal atrial fibrillation is catheter ablation using radiofrequency. However, measurable morbidity and significant costs and time are associated with this modality of treatment of permanent or persistent atrial fibrillation. In order to overcome these issues, a transesophageal...
Accurately estimating the strain is one of the fundamental challenges in ultrasound (US) elastography. Yet, most of the techniques used in elastography remain mono-or bi-dimensional and may lead to noisy elastograms if significant lateral or out-of-plane motion occurs. Moreover, the recent development of 2D transducer arrays to acquire 3D US RF data provides new prospects for medical US applications...
Optoacoustic imaging is a new promising medical imaging modality combining the benefits of optical and acoustical methods. The strong scattering behaviour of biological media limits the imaging depth of pure optical modalities like OCT (optical coherence tomography). On the other hand, the field of applications of ultrasound is sometimes limited by the lack of contrast in acoustical impedance between...
