Image registration is an important problem in image processing, especially in medical
imaging. It is a hard optimization problem with objective function that is not appropriate for …

Coronary artery disease (CAD) is the leading cause of death around the world. One of the
most common imaging methods for diagnosing CAD is the X-ray angiography (XRA) …

X-ray coronary angiography can provide rich dynamic information of cardiac and vascular
function. Extracting contrast-filled vessel from the complex dynamic background (caused by …

Cerebral X-ray digital subtraction angiography (DSA) is the standard imaging technique for
visualizing blood flow and guiding endovascular treatments. The quality of DSA is often …

Accurate coronary artery segmentation in X-ray angiographic images is a challenging task
due to the low image quality and presence of artifacts. This paper proposes an automatic …

We outline a generic framework for single-frame, detector-domain material decomposition.
The method involves a segmentation and a background estimation step yielding a virtual …

Objective: Automatic vascular enhancement in X-ray cineangiography is of crucial interest,
for instance, for better visualizing and quantifying coronary arteries in diagnostic and …

This study investigates how the translational velocity of phospholipid-coated bubbles
caused by acoustic radiation force depends on their size. The translations of bubbles with …

Image registration between planning CT images and cone beam-CT (CBCT) images is one
of the key technologies of image guided radiotherapy (IGRT). Current image registration …

Automatic vascular enhancement is crucial to vascular structure identification in X-ray
angiographic (XRA) image sequences. In this work, we propose a novel spatio-temporal …
