Biplane modality is frequently used in medical ultrasound imaging applications. Crossed array configurations, in which two orthogonal 1-D arrays co-exist on the same area, are particularly suitable for biplane imaging. However, the imaging performanc

When Capacitive Micromachined Ultrasonic Transducers (CMUTs) are coupled with water, they show high front-face acoustic reflectivity, due to the impedance mismatch between the transducer substrate material, typically based on silicon, and the propaga
