This paper reports a new water-immersible single-axis scanning mirror using hybrid polymer and elastomer hinges to achieve both high scanning resonance frequencies and large tilting angles for high-speed and wide-field 3D ultrasound imaging. To demonstrate the concept, a prototype scanning mirror is designed, fabricated, and characterized. The fast- and slow-scanning were achieved by integrating stiff BoPET (biaxially oriented polyethylene terephthalate) and soft elastomer PDMS (Polydimethylsiloxane) hinges, respectively. The testing results have shown a resonance frequency of 270 for the BoPET hinges and a resonance frequency of 10 for the PDMS hinges when the scanning mirror was immersed in water. 3D ultrasound imaging is demonstrated by combining the fast- and slow-scanning together to provide both an augmented field of view (FoV) and high local imaging volume rate.
本文报道了一种新型的水浸式单轴扫描镜，它采用混合聚合物和弹性体铰链，以实现高扫描共振频率和大倾斜角度，用于高速和宽视野三维超声成像。为了验证这一概念，设计、制造并表征了一个扫描镜原型。通过分别集成刚性的双向拉伸聚对苯二甲酸乙二酯（BoPET）和柔性弹性体聚二甲基硅氧烷（PDMS）铰链来实现快速扫描和慢速扫描。测试结果表明，当扫描镜浸入水中时，BoPET铰链的共振频率为270Hz，PDMS铰链的共振频率为10Hz。通过将快速扫描和慢速扫描结合在一起，展示了三维超声成像，以提供扩大的视野（FoV）和高局部成像体素率。
