A review of algorithm research progress for non-rigid medical image registration

Abstract

At present, the registration algorithms based on the rigidity medical image are developed and also used well in actual clinical. But the non-rigid medical image registration algorithms are still developing, therefore domestic and foreign researchers put forward various non-rigid registration algorithms. Firstly, this paper analyses the necessity of non-rigid registration. Secondly, specifies the recent typical non-rigid registration algorithms, and summarizes the fundamental principles and research progresses of these algorithms. Thirdly, in medical images, demonstrates applications of the non-rigid registration algorithms from three different properties. Finally, discusses the trend of non-rigid registration algorithms in future.
