SS-CADA: A Semi-Supervised Cross-Anatomy Domain Adaptation for Coronary Artery Segmentation [PDF]
arXiv, 2021 The segmentation of coronary arteries by convolutional neural network is promising yet requires a large amount of labor-intensive manual annotations. Transferring knowledge from retinal vessels in widely-available public labeled fundus images (FIs) has a potential to reduce the annotation requirement for coronary artery segmentation in X-ray angiograms

The Epicardium and Coronary Artery Formation
Journal of Developmental Biology, 2013 The coronary system is the network of blood vessels that nourishes the heart muscle. After birth, proper coronary blood circulation is required to support heart homeostasis, and altered coronary function frequently leads to myocardial ischemia ...

Robust Implementation of Foreground Extraction and Vessel Segmentation for X-ray Coronary Angiography Image Sequence [PDF]
arXiv, 2022 The extraction of contrast-filled vessels from X-ray coronary angiography (XCA) image sequence has important clinical significance for intuitively diagnosis and therapy. In this study, the XCA image sequence is regarded as a 3D tensor input, the vessel layer is regarded as a sparse tensor, and the background layer is regarded as a low-rank tensor ...

Blood Vessel Geometry Synthesis using Generative Adversarial Networks [PDF]
arXiv, 2018 Computationally synthesized blood vessels can be used for training and evaluation of medical image analysis applications. We propose a deep generative model to synthesize blood vessel geometries, with an application to coronary arteries in cardiac CT angiography (CCTA).
