将简约叠后偏移扩展到三维。通过沿着每个入射波方向(由接收器处的局部倾斜叠加确定)跟踪单条射线，射线跟踪可以嵌入偏移中。这种方法大大减少了所需的计算机时间和磁盘空间，因为不需要构建和保存图像时间图；3D迁移可以在工作站或个人计算机上执行，而不是使用超级计算机或集群。
Parsimonious post‐stack migration is extended to three dimensions. By tracing single rays back along each incident wave direction (as determined by a local slant stack at the receivers), the ray tracing can be embedded in the migration. This approach significantly reduces the computer time and disk space needed because it is not necessary to build and save image time maps; 3D migration can be performed on a workstation or personal computer rather than using a supercomputer or cluster.
