摘要
光声成像(PAI)是一种前景广阔的新型医学成像方法,具有光学分辨率和声学穿透深度的优点。透明超声换能器(TUT)作为一种应用于 PAI 的新型设备,可将激光束和声束同轴结合,从而提高成像质量。透明压电材料是开发压电 TUT 的关键。然而,由于铁电畴引起的双折射和光散射,很难制备出既有高透光率又有优异压电性的透明压电材料。本研究成功制备了掺杂 2.5 mol% Sm 的 0.72Pb(Mg1/3Nb2/3)O3-0.28PbTiO3(PMN-PT)陶瓷,其压电系数 d33 为 1460 pC N-1,近红外(NIR)光学透过率为 69%,并对其光学、微观结构、铁电和介电特性进行了全面研究。随后,以制备的陶瓷为基础,制作了一个直径为 3 毫米的光声同轴探头,包括一个透明超声换能器。TUT 的中心频率 (fc) 为 18.5 MHz,-6 dB 带宽为 20%,有效机电因子 (keff)keff) 高达 0.62。此外,通过对体内动物和模型进行 PA/US 双模态成像,首次证实了微型探针的成像能力,这表明所提出的透明压电陶瓷在光声/超声成像方面具有巨大潜力。
As a promising new medical imaging method, photoacoustic imaging (PAI) has the advantages of optical resolution and acoustic depth of penetration. The transparent ultrasound transducer (TUT), as a novel device applied to PAI, can combine the laser and acoustic beam coaxially to improve the imaging quality. Transparent piezoelectric materials are the key to developing piezoelectric TUTs. However, due to the birefringence and light scattering caused by ferroelectric domains, it is very hard to prepare transparent piezoelectric materials with both high optical transmittance and excellent piezoelectricity. In this study, 2.5 mol% Sm-doped 0.72Pb(Mg1/3Nb2/3)O3-0.28PbTiO3 (PMN-PT) ceramic with a piezoelectric coefficient d33 of 1460 pC N-1 and an optical transmission of 69% at Near-Infrared (NIR) is successfully prepared, and its optical, microstructure, ferroelectric and dielectric properties are fully studied. Subsequently, a 3 mm-diameter photoacoustic coaxial probe is fabricated, involving a transparent ultrasound transducer based on the prepared ceramic. The TUT has a center frequency (fc) of 18.5 MHz, a −6 dB bandwidth of 20%, and a high effective electromechanical factor ( of 0.62. In addition, the imaging capability of the miniature probe is firstly confirmed through PA/US dual-modality imaging of in-vivo animals and phantoms, which indicates that the proposed transparent piezoelectric ceramic has great potential for photoacoustic/ultrasound imaging.
