The present invention is directed to a system and method which makes a phased array look like a curved array for purposes of performing spatial compounding calculations. In one embodiment, the phased array is treated as though it were a curved array by creating both a virtual apex and a virtual radius of curvature. Based on this transformation, standard spatial-compounding resampling tables can be used just as they are with curved arrays. In one embodiment, after the data is compounded to form the target image, certain data is removed prior to the actual display. This removed data represents data generated by virtual rays the prior to the physical skin line of the phased array. 本发明涉及形成对象的超声波图像的方法和系统。在个实施例中，通过产生虚拟顶点和虚拟曲率半径来将所述相控阵处理成好像是曲面阵列样。基于该转化，可以使用标准空间复合重采样表，正像其被用于曲面阵列那样。在个实施例中，在复合数据以形成目标图像后，在实际显示之前移除某些数据。所移除的数据表示在相控阵的物理皮肤线之前通过虚拟射线产生的数据。
