(A) A c-arm CT angiogram demonstrating the detection of 4 PFOB injection sites in a rabbit medial thigh, while unlabeled capsules in the left thigh no detectable. (B) 19F MRI of the same rabbit showing one-to-one correspondence to the injection location on c-ARM CT. (C) Co-registering of threshold c-arm CT image of a rabbit with 6 PFOB Caps injection sites (gray) and postmortem 3D rendering volume of each injection sites (color) demonstrating the location of opacities on c-arm CR image is representative of PFOB Caps injections. Registration error for each injection site from a representative rabbit is shown.
