Cover Story: Coronary optical coherence tomography (OCT) is a light-based, intravascular imaging modality that can visualise plaque components in high resolution. This resolution is critical when identifying vulnerable plaque features, such as thin cap fibroatheroma, which dramatically increase the risk of future major adverse cardiac events (MACE). However, extracting these features is often carried out manually, a tedious and time-consuming process that limits its clinical utility. Computational techniques are emerging to automate this process, enabling near-real time image analyses and subsequent three-dimensional simulation to assist in identifying patients most at risk of future MACE. Here, we discuss recent advances in these techniques and their ability to identify the coronary lumen, artery layers, plaque components, and subtypes and stents. View this paper
