TL;DR: In this paper, the authors proposed a method and system for quickly calculating a vascular pressure difference, which consists of a data receiving module, a geometric model building module and a pressure difference calculation module.

TL;DR: In this paper, a 3D blood vessel boundary segmentation method and system consisting of a preprocessing module, a first coordinate transformation module which transforms an image into an image under a polar coordinate system, an image artifact identification module which determines an artifact in the image and generates an artifact mask image, a vessel cavity center locating module which determined a blood vessel center in the original image, and a second coordinate transform module which transformed the determined image of the blood vessel cavity centre into a new image under the polar coordinate systems, and removes an artifact from the new image according to the artifact

TL;DR: This is the first time to show that OCT-based FFR can be computed online in the catheterization laboratory, and bears the potential of improving integration of intracoronary OCT imaging and physiological assessment in patients with coronary artery disease.

TL;DR: In this article, a plaque stability determination method and system based on optical coherence tomography was proposed, which consists of an image collection module, an image reception module, image processing module and a result display module.
