提出了一种用于 3D 实时声学成像中回波数据并行处理的最佳横向滤波器组。它基于使用编码孔径换能器或具有编码激励的发射器阵列的系统的成像方程的离散线性时域形成。这两种方法在数学上是等效的，并且产生一种成像系统架构，该架构基于使用一组横向滤波器对回波数据的采样向量进行并行处理。滤波器系数是通过伪逆算子获得的，该算子旨在解耦从不同图像线接收到的回波。<<ETX>>
An optimal transversal filter bank for parallel processing of echo data in 3-D real-time acoustical imaging is proposed. It is based on discretized linear time-domain formation of the imaging equation for systems that use either coded-aperture transducers or transmitter arrays with coded-excitation. The two approaches are mathematically equivalent and result in an imaging system architecture which is based on parallel processing of a sampled vector of echo data with a bank of transversal filters. The filter coefficients are obtained through a pseudoinverse operator which is designed to decouple echoes received from different image lines.<<ETX>>
