Levent Degertekin1, Maysam Ghovanloo1 Georgia Institute of Technology, Atlanta, GA University of Leeds, Leeds, United Kingdom 1 2 Intracardiac echocardiography (ICE) provides real-time ultrasound imaging of the heart anatomy from inside, guiding interventions like valve repair, closure of atrial septal defects (ASD) and catheter-based ablation to treat atrial fibrillation. With its better image quality and ease of use, ICE is becoming the preferred imaging modality over transesophageal echography (TEE) for structural heart interventions. The existing commercial ICE catheters, however, offer a limited 2D or 3-D field of view despite catheters utilizing large number of wires. In these catheters, each element in the ICE array is connected to the backend dataacquisition channel with a separate wire, which is a critical barrier for improving
