Abstract
High frame rate 3D intracardiac echography (3D-ICE) might enable full-volumetric flow, tissue, and electro-mechanical wave tracking in the heart, thus supporting complex interventional procedures. Designing ICE transducers is very challenging due to the constraints imposed by the catheter's diameter on the transducer aperture and cable accommodation within the shaft. Current ICE probes only offer a 2D or limited 3D field of view at low frame rates. This work presents the design, fabrication, and characterization of an ICE prototype transducer aiming at high frame rate 3D imaging with a large field of view.
