  • Side-looking Intravascular Ultrasound Systems (IVUS) systems provide high resolution cross-sectional images of vascular structure. However, blood velocity estimation is hampered by the orthogonality of the primary blood flow direction to the imaging plane, and do not image in front of the catheter. A forward-looking aperture would improve the ability to guide interventions and allow Doppler processing for improved blood speed estimates; however, catheter-based systems delivered over a guide… CONTINUE READING
