Live Volumetric Ultrasound Imaging
Live volumetric imaging (LVI)® is a breakthrough ultrasound transducer technology that enables catheter-based real-time 3D intracardiac echo (ICE) imaging. The LVI catheter uniquely provides the combined desired features of full volume ultrasound imaging with high frame rate, deep scan depth, and good resolution. The goal is to enable better image guidance to improve accuracy and reduce risk for cardiac transcatheter interventional therapies that are done today with limited direct visualization of the endocardial tissue.
LVI's enabling technology is its integrated piezoelectric micromachined ultrasound transducer (pMUT), a breakthrough advance in ultrasound transducer manufacturing and miniaturization. Full matrix phased array transducers are fabricated using semiconductor microelectromechanical systems (MEMS) manufacturing techniques, providing a more manufacturable, lower cost approach to produce the miniaturized matrix phased arrays necessary for catheter-based real-time 3D ultrasound imaging.
