中文摘要	Coronary artery edges must be accurately identified for proper diagnosis of heart conditions. This paper presents a T-Snake model based on orthogonal grids to semi-automatically detect the edges of coronary arteries. A mathematical morphology transform is used to remove the fake edges caused by asymmetries of the gray scale in the blood vessel and in the larger tissues. The method then forms the edge contour along the nodes of an orthogonal grid and calculates the contour based on the node energy. The energy function does not include the elastic energy, but includes an area energy added as a part of the 'inflation' energy. Clinical results with coronary artery images show that this method is effective with both magnetic resonance imaging (MRI) and X-ray computed tomography (CT) images.
