Single injection dual phase CBCT technique ameliorates results of trans-arterial chemoembolization for hepatocellular cancer [PDF]
, 2017 Cone-beam CT (CBCT) application to the field of trans-arterial chemoembolization has been recently the focus of several researches. This imaging modality is performed with a rotation of the C-arm around the patient, without needs of patient repositioning.

Deep Neural Networks for ECG-free Cardiac Phase and End-Diastolic Frame Detection on Coronary Angiographies [PDF]
arXiv, 2018 Invasive coronary angiography (ICA) is the gold standard in Coronary Artery Disease (CAD) imaging. Detection of the end-diastolic frame (EDF) and, in general, cardiac phase detection on each temporal frame of a coronary angiography acquisition is of significant importance for the anatomical and non-invasive functional assessment of CAD.

Automated Characterization of Stenosis in Invasive Coronary Angiography Images with Convolutional Neural Networks [PDF]
arXiv, 2018 The determination of a coronary stenosis and its severity in current clinical workflow is typically accomplished manually via physician visual assessment (PVA) during invasive coronary angiography. While PVA has shown large inter-rater variability, the more reliable and accurate alternative of Quantitative Coronary Angiography (QCA) is challenging to ...

Unsupervised Deep Learning for MR Angiography with Flexible Temporal Resolution [PDF]
arXiv, 2020 Time-resolved MR angiography (tMRA) has been widely used for dynamic contrast enhanced MRI (DCE-MRI) due to its highly accelerated acquisition. In tMRA, the periphery of the k-space data are sparsely sampled so that neighbouring frames can be merged to construct one temporal frame.

An Effect of Spatial Filtering in Visualization of Coronary Arteries Imaging [PDF]
International Journal of Computer Science & Information Technology
(IJCSIT), Vol. 2, No. 1, 2009, PP: 35-40, 2011 At present, coronary angiography is the well known standard for the diagnosis of coronary artery disease. Conventional coronary angiography is an invasive procedure with a small, yet inherent risk of myocardial infarction, stroke, potential arrhythmias, and death.
