| P1F082-05. PIN-PMN-PT Single Crystal High Frequency Ultrasound Transducers for Medical Applications |
| High frequency ultrasonic transducers were fabricated using lead indium niobate-lead magnesium niobate-lead titanate (0.24PIN-0.44PMN-0.32PT) as the active piezoelectric material. The measured center frequency and bandwidth of the device were 35 MHz and 48 % respectively. The electrical impedance magnitude was 71 Ù and phase was - 38°. Insertion loss was measured to be 15 dB. A phantom which consists of 20-µm tungsten wires was imaged to assess spatial resolution of the transducer. |
