Pixel shift problem in PET-MRI fusion. Shown are the input PET image, MRI image, and each method’s fusion result. The upper right enlargement displays the binary difference image between the red area in each fusion result and the corresponding PET image; the lower right enlargement shows the binary difference image between the green area and the corresponding MRI image.
