Figure 7From: Magnetic microbubble-mediated ultrasound-MRI registration based on robust optical flow modelUS-MRI registration (from (c) to (g)) by different values of parameter λ 2 ( λ 1 = 5, λ 3 = 1) without MMBs based on the proposed methods. (a) US image segmentation. (b) MRI segmentation. (c) (λ2 = 1e - 4). (d) (λ2 = 1e - 2). (e) (λ2 = 1). (f) (λ2 = 1e + 2). (g) (λ2 = 1e + 4). (h) subtraction result between (c) and (b). (i) subtraction result between (d) and (b). (j) subtraction result between (e) and (b). (k) subtraction result between (f) and (b). (l) subtraction result between (g) and (b).Back to article page
