A computer-implemented method for aligning sub-volumes includes receiving a data volume, providing a plurality of parameters of the sub-volumes, and determining a start point of each of the two or more sub-volume according to the plurality of parameters. The method further includes determining an amount of mis-alignment of the two or more sub-volumes, and shifting a start point of each sub-volume to align the start points with a grid of a virtual volume. The method may include determining a feature in the two or more sub-volumes, which have been aligned. The method may include visualizing the aligned sub-volumes.
