Ultrasonography based on traditional bulk piezoelectric transducers has been established as an inexpensive and safe medical imaging modality. By borrowing techniques from the microelectronics industry, the performance of the ultrasound transducer can be dramatically improved and new applications become feasible. Dr. Arman Hajati and his co-workers from Fujifilm Dimatix (FDMX), Santa Clara CA, have developed a high performance ultrasound transducer technology. This novel transducer technology is based on an array of three-dimensional micromachined semi-ellipsoidal piezoelectric domes made of the high-quality PZNT thin film developed at FDMX.
