Key Performance Parameters of a Contemporary Diagnostic Ultrasound Transducer

Broadband All-Optical Ultrasound Transducer

Real-time three-dimensional (3D) high-resolution ultrasound imaging requires 2D phased arrays operating at frequencies higher than 50 MHz, which poses a great challenge for piezoelectric technologies. A promising alternative is an optoacoustic array relying on optical generation and detection of ultrasound. We present an all-optical ultrasound transducer, which consists of a 2D gold nanostructu...
