Abstract:
A method and system for automatically aligning multiple MR volumes in whole-body MR scans is disclosed. The method and system are capable of automatic alignment of leg-volumes in whole-body MR scans that is insensitive to leg movement. In order to align upper and lower MR volumes, an automatic determination may be made that a junction between the upper and lower MR volumes is in a leg region. The lower MR volume is then divided into left and right regions, and each of the left and right regions are independently aligned with the upper MR volume. One of the left and right regions is then adjusted with respect to the other one to compensate for shifting of the legs with respect to each other.
