Pulmonary Embolism Vascular Segmentation in CT Angiography
Qi Gao, Huai An Li · Applied Mechanics and Materials · 2013
Pulmonary embolism mortality rate is very high disease, especially for acute pulmonary embolism with other disease mortality. Treatment of pulmonary embolism method is mainly to drug therapy. Pulmonary embolism in the acute phase of drug treatment strategies is mainly for anticoagulation and thrombolysis. Through the lungs scanning, decision of thrombolysis success or fail. This paper puts forward a kind of algorithm that analysis quantitatively the degree of thrombolysis by the computer. Firstly, making use of the Hessians eigenvalue and diffuse equation enhance pulmonary embolism vessel, and then pulmonary embolism vessel segmentation based on a LEVEL-SET. At lastly, According to the eigenvalue of blood vessels, remove the blood vessels edge line, and the rest relevant to edge point. According to the each point of eigenvector and eigenvalue, quantitative analysis of the degree of thrombolysis.
