Results of the segmentation process. (a) One slice of the ultrasound volume of the tibia phantom. (b) Same slice in A with the CT segmentation overlapped. (c) Same slice in A with the result of the ultrasound segmentation overlapped. (d) Same slice in A with the result of the ultrasound and CT segmentations overlapped. (e) Ultrasound and CT reference segmentations overlapped. (f) 3D reconstruction of the resulting ultrasound segmentation of one experiment. (g) 3D reconstruction of the CT reference segmentation. (h) 3D reconstructions ultrasound and CT overlapped.
