Figure 9From: Magnetic microbubble-mediated ultrasound-MRI registration based on robust optical flow modelUS-MRI registration based on the proposed method without MMBs ( λ 1 = 5, λ 2 = 1 e +2, λ 3 = 1). (a) US image segmentation. (b) MRI segmentation. (c) subtraction result between (a) and (b). (d) optical flow field. (e) registered result of (a). (f) subtraction result between (e) and (b). (g) US image. (h) registered US image.Back to article page
