Regisration of myocardial perfusion MRI images

Medical image registration is the first step for image fusion and other imaging process. It has a fully use in medical imaging process and analysis. In this paper, a novel method of image registration for myocardial perfusion magnetic resonance imaging(MRI) based on image segmentation and correlation function was presented. This iterative method utilized correlation function as the matching criterion to determine the best matching parameters through the maximization of the correlation function. The advantage of this technique is that it fully considered the movements of the patients, such as breathing, head nodding, as well as the changes of myocardial perfusion signals.EI02199-2022
