摘要

四维超声成像的进步通过减少长期存在的操作员依赖性挑战，为生物医学研究开辟了新的视角。广泛的研究工作集中在开发用于4D成像的下一代2D换能器阵列上。在这里，我们提出了一个基于六边形传感器元件的紧凑二维阵列设计。我们证明了二维六边形阵列提供了一个最佳的紧凑采样，导致较低的光栅瓣电平和改进的成像质量相比，传统的方形换能器元件阵列。提出了一种由六边形换能器元件组成的原型阵列，并对其进行了表征，证明了其成像能力。

A compact 2D matrix array comprised of hexagonal transducer elements for fast volumetric ultrasound imaging.

Advances in 4D ultrasound imaging open new perspectives in biomedical research by reducing the long-standing challenge of operator dependency. Extensive research efforts are focused on developing next generation of 2D transducer arrays for 4D imaging. Here, we present a compact 2D array design based on hexagonal-shaped transducer elements. We demonstrate that 2D hexagonal arrays provide an optimal compact sampling, resulting in lower grating lobe levels and an improved imaging quality compared to conventional square-shaped transducer element arrays. A prototype array made of hexagonal transducer elements is presented, and its characterization is provided, demonstrating its imaging capabilities.
