Application and research of non-rigid medical image registration algorithm
Qing Liu · Jisuanji yingyong yanjiu · 2009
Rigid registration is unable to meet clinical needs in many cases,because many deformations are non-rigid and non-linear. This paper proposed a new registration algorithm which combined the point restriction of thin-plate spline with mutual information. It performed the global registration and then refined the result using the mutual information. Experiment proves that the algorithm can obtain a good registration results.
