Abstract:
As a new neuroimaging method, functional magnetic resonance (fMRI) with its importance of data processing has been widely recognized by neurology and cognitive psychology. Focusing on the realignment section in fMRI image preprocessing, this paper comprehensively describes the registration principle of SPM, an internationally-known software package which is specially designed for cerebral function imaging. An improved registration method is presented which effectively increases the accuracy. In addition, choosing the ratio of SSD and NMI as the registration measure can compensate for the limitation of using single measurement, which improves the robustness and reliability of the registration process. Experimental results prove the feasibility of this method.
