Figure 5 Intravascular ultrasound (IVUS) versus ocular coherence tomography (OCT) comparison (intimal hyperplasia). This image demonstrates an OCT image (A) and IVUS image (30 MHz) (B). Both images were generated with 2.9-F catheters. The IVUS catheters were not reused. In the OCT image the intimal hyperplasia is seen, whereas in the IVUS image, it is difficult to detect. The bar in the OCT image is 500 µm. Reprinted, with permission, from Tearney et al. (6).
