Abstract:: Abstract: Due to the complex adhesion and overlapping of human carotid artery and plaque in luminance distribution and morphology, clearly reflecting the space-occupying of plaque in carotid artery only depending on CT and MRI files obtained by the ordinary way is of high clinical significance. A novel method which uses parametric spline to define the cutting ball family for obtaining the voxels near the carotid artery is presented, and it can gain the visual effect that is basically consistent with the surgical anatomy of carotid artery plaque through the enhancement of contrast luminance between carotid and plaque and geometric scaling-up. The proposed method is compared with the common used blood vessel segmentation method based on the stretching along the vascular centerline. The experiments show that the proposed method can provide real-time visualization for the segmentation of carotid plaque tissues, which is conducive to the relevant treatments and efficacy analysis.
