Abstract—A method is presented for generating ultrasound images in imaging devices with phased arrays, based on decomposition of the recorded spatiotemporal signal into a spectrum of plane pulsed waves. A case is considered when a number of intermediate layers with unknown thicknesses and sound speeds are located between the ultrasound array and the visualization region. The method is based on measuring the delays of the spectral components of plane waves transmitted through layers and reflected from the boundary of the visualization region, as well as on compensating for these delays when summing the spectral components scattered by inhomogeneities in the visualization region.

通过未知参数的层进行超声成像

摘要—提出了一种方法，该方法基于将记录的时空信号分解为平面脉冲波频谱，从而在具有相控阵的成像设备中生成超声图像。考虑当超声波阵列和可视化区域之间存在许多厚度和声速未知的中间层时的情况。该方法基于测量透射通过层并从可视化区域的边界反射的平面波的频谱分量的延迟，以及在对由可视化区域中的不均匀性所散射的频谱分量求和时对这些延迟的补偿。
