论文摘要
在医疗领域，通常使用压电阵列进行超声检测，这使人们能够在多个位置同时绘制声场。在这项工作中，我们开发了一种新的方法，该方法通过使用循环hadamard模式编码的二进制声掩码来将单元超声检测器转换为有效检测阵列。通过扫描检测器前面的掩码，我们获得了一个多路复用的测量数据集，从该数据集通过该数据集进行了分析构建声场的映射。我们通过将单元素超声检测器转换为具有多达59个元素的1D阵列来实验证明我们的方法。
In the medical fields, ultrasound detection is often performed with piezoelectric arrays that enable one to simultaneously map the acoustic fields at several positions. In this work, we develop a novel method for transforming a single-element ultrasound detector into an effective detection array by spatially filtering the incoming acoustic fields using a binary acoustic mask coded with cyclic Hadamard patterns. By scanning the mask in front of the detector, we obtain a multiplexed measurement dataset from which a map of the acoustic field is analytically constructed. We experimentally demonstrate our method by transforming a single-element ultrasound detector into 1D arrays with up to 59 elements.
