A method for processing an image of coronary arteries given by an intensity function I(x,y). A function z(x,y) is obtained describing the heart surface. The image is then processed to produce an image having an intensity function I'(x,y) where I' is obtained in a calculation involving...
During this procedure, a catheter containing a guidewire is inserted through an artery in the thigh, and guided by a cardiologist through the arteries until it reaches the blocked coronary artery. The catheter is stopped immediately before the stenosis or blockage, and the guidewire is guided ...

The heart has four valves: tricuspid, pulmonary, mitral, and aortic. These valves ensure that blood flows in the correct direction. The heart’s blood supply comes from the right and left coronary arteries. Deoxygenated blood from the heart is drained by the coronary sinus, which includes the...
Tangier disease with continuous massive and longitudinal diffuse calcification in the coronary arteries : demonstration by the sagittal images of intravascular ultrasonography. 来自 Semantic Scholar 喜欢 0 阅读量: 23 作者: R Komuro,S Yamashita,S Sumitsuji,KI Hirano,T Maruyama,M Nishida,F Matsuura...
This paper proposes a novel global feature embedded network for better coronary arteries segmentation in 3D coronary computed tomography angiography (CTA) data. The global feature combines multi-level layers from various stages of the network, which contains semantic information and detailed features, ...
A method for processing an image of coronary arteries given by an intensity function I(x,y). A function z(x,y) is obtained describing the heart surface. The image is then processed to produce an image having an intensity function I′(x,y) where I′ is obtained in a calculation ...
Moreover, when an artery is diseased, it may appear as a non-continuous structure of widely varying width and image intensity. Denning the boundaries of the coronary arteries is an important and necessary step for further analysis and diagnosis of coronary disease. For this purpose, we developed...
We commented that the diagnosis of Kawasaki Disease was often clinical in the acute stage and the absence ofcardiac involvement did not exclude it.Another 25% will regress in size and about 15% progress to stenosis or obstruction of the coronary arteries. They may result in chest pain, ...
