Intravascular Ultrasound

Cardiac Cath Lab Director, 2011
Coronary angiography is the gold standard for evaluating coronary atherosclerotic heart disease, yet it has well-known limitations. Intravascular ultrasound (IVUS) is an invasive technique that is used to improve the assessment and management of coronary artery disease.

Intravascular ultrasound

Techniques in Vascular and Interventional Radiology, 2001
Intravascular ultrasound imaging, in which a catheter-based miniature sonographic transducer is introduced into vessels, provides high-resolution, cross-sectional, real-time imaging of the vessel wall and lumen. It has been found to be useful as both a diagnostic and therapeutic adjunct in the evaluation and management of various arterial and venous ...

Robust segmentation of arterial walls in intravascular ultrasound images using Dual Path U-Net.

Ultrasonics, 2019
A Fully Convolutional Network (FCN) based deep architecture called Dual Path U-Net (DPU-Net) is proposed for automatic segmentation of the lumen and media-adventitia in IntraVascular UltraSound (IVUS) frames, which is crucial for diagnosis of many ...
