YU Ya · Journal of Chongqing University. English Edition · 2003
Medical image registration, which is the precondition of medical image fusion, is a highlight of present medical image processing, and has important values in clinical diagnosis and treatment. This paper firstly presents a classification of medical image registration methods in terms of seven standards, then summarizes some major registration methods from three aspects, such as moment and principal axes method, mutual information, and correlation method etc. Although there are many algorithms at present, no registration method could come up with ideal requirements in every aspect because of its difficulty and complexity. Consequently registration method has to make its choice between accuracy, velocity, automation extent and other aspects. However, with the development of computer technology and medical imaging, the registration technology of medical image is bound to develop quickly.
