Automatic Nonrigid Registration for Tracking Brain Shift During Neurosurgery

Intraoperative imaging is used more frequently today since this enables the surgeon to localize structures inside the brain more accurately and helps to detect shape changes. In order to combine information's derived at different time points, it describes a nonrigid registration algorithm that aligns MR scans of the brain. Based on a set of feature points, an initial sparse estimate of the displacement field is found by optimizing a local cost function.
