IVUS-OCT imaging of a rabbit abdominal aorta in vivo. (I) Three-dimensional cut-away rendering of the volumetric data set acquired with an intravascular catheter in abdominal aorta of a live rabbit. The volume comprises 288 frames of images acquired in 4 s during the injection of iohexol at a rate of 3 ml/s. Red, artery wall; semi-transparent white, lipid. Circular cross-section IVUS (IIa) (IIIa) (IVa) OCT (IIb) (IIIb) (IVb) fused IVUS-OCT (IIc) (IIIc) (IVc) image pairs and the corresponding H&E histology photos (IId) (IIId) (IVd) at locations 1, 2 and 3 denoted in (I). Arrows point at lipid-rich plaque regions. Scale bar: 0.5 mm. The shape of this artery changed between in vivo imaging and histology due to the reduced intra-lumen pressure after this artery was harvested. Reprinted from [26], with permission.
