Vascular Segmentation Using Level Set Method
نویسندگان
چکیده
In this paper, we propose a two-stage level set segmentation framework to extract vascular tree from magnetic resonance angiography(MRA). First, we smooth the isosurface of MRA by anisotropic diffusion filter. Then this smoothed surface is treated as the initial localization of the desired contour, and used in the following geodesic active contours method, which provides accurate vascular structure. Results on cases demonstrate the effectiveness and accuracy of the approach.

Vascular segmentation plays an important role in medical image analysis. A novel technique for the automatic extraction of vascular trees from 2D medical images is presented, which combines Hessian-based multiscale filtering and a modified level set method. In the proposed algorithm, the morphological top-hat transformation is firstly adopted to attenuate background. Then Hessian-based multisca...
متن کاملSegmentation of the Vascular Tree in CT Data Using Implicit Active Contours
We propose an algorithm for the segmentation of blood vessels in the kind of CT-data typical for diagnostics in a clinical environment. Due to poor quality and variance in the properties of the data sets a two level approach using implicit active contours is chosen for the task. A fast pre-segmentation using the fast marching method followed by propagation of a sparse field level set allows a r...

متن کاملMr Image Segmentation Using Level Set Method
In this paper, we proposed a mechanism based on level set method to find the bone marrow parts of the knee MR images. The segmentation can be divided into three steps. The first step is to do rough segmentation on the image using level set method. The second step is to do further segmentation on the result of level set method, and then eliminating the fragments caused by level set method. The t...
