摘要
据报道，掺钐的 Pb（Mg1/3Nb2/3）O3-0.28PbTiO3（PMN-0.28PT）陶瓷表现出非常大的压电响应（d33~1300 pC/N），可与 PMN-0.30PT 单晶相媲美。基于掺杂 Sm 的 PMN-0.28PT 陶瓷，设计和制造了一种中心频率高于 30 MHz 的高频超声换能器，用于血管内超声成像，并通过超声脉冲回波测试研究了换能器的性能。此外，还利用所制造的高频换能器进行信号采集和处理，构建了猪血管壁的二维和三维超声图像。通过 IVUS 换能器获得的血管壁细节表明，掺杂 Sm 的 PMN-0.28PT 陶瓷有望成为高频换能器的候选材料。
High Frequency Ultrasound Transducer Based on Sm-Doped Pb(Mg1/3Nb2/3)O3-0.28PbTiO3 Ceramic for Intravascular Ultrasound Imaging.
Sm-doped Pb(Mg1/3Nb2/3)O3-0.28PbTiO3 (PMN-0.28PT) ceramic has been reported to exhibit very large piezoelectric response (d33~1300 pC/N) that can be comparable with PMN-0.30PT single crystal. Based on the Sm-doped PMN-0.28PT ceramics, a high frequency ultrasound transducer with the center frequency above 30 MHz has been designed and fabricated for intravascular ultrasound imaging, and the performance of the transducer was investigated via ultrasound pulse-echo tests. Further, for a porcine vessel wall, the 2D and 3D ultrasound images were constructed using signal acquisition and processing from the fabricated high-frequency transducer. The obtained details of the vessel wall by the IVUS transducer indicate that Sm-doped PMN-0.28PT ceramic is a promising candidate for high frequency transducers.
