Automatic carotid centerline extraction from three-dimensional ultrasound Doppler images
2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014Vessel lumen centerline extraction is an important issue for the intra-operative guidance of endovascular instruments; furthermore, vessel centerline is often used as a reference position in many hemodynamic studies, especially in carotid arteries. In this work we propose an innovative method for the extraction of carotid vessels centerline from three ...

Automatic Aortic Dissection Centerline Extraction Via Morphology-Guided CRN Tracker
IEEE Journal of Biomedical and Health Informatics, 2021Aortic dissection (AD) centerline extraction has important clinical value in the quantitative diagnosis and treatment of AD disease. However, AD centerline extraction is a difficult task and quantitative evaluation is rarely studied. In this work, we propose a fully automatic algorithm to extract AD centerline based on a convolutional regression ...

Vascular Cross-Section Extraction Algorithm Based on Centerline
2019 9th International Conference on Information Science and Technology (ICIST), 2019Vascular cross-section is an important basis for computer-assisted diagnosis of vascular diseases. In this study, a new algorithm of calculating cross-sectional area of blood vessels was proposed. The algorithm first extracts centerline of the blood vessel from the image through thinning algorithm, and obtains neighborhood coordinates of each point on ...

Extraction of blood vessel centerlines on retinal images
2010 15th National Biomedical Engineering Meeting, 2010Vessel extraction has important role to determined eye's vessels changing that are occured by systemetic disease. In this study;included the extraction of vessel's centerlines. Since blood vessels often present poor contrast and narrow vessels width, the multiscale matched filter used with thresholding method used to extraction of blood vessels ...

3-D centerline extraction for virtual cardiovascular endoscopy
2014 11th International Computer Conference on Wavelet Actiev Media Technology and Information Processing(ICCWAMTIP), 2014This paper discusses centerline extraction algorithms for virtual cardiovascular endoscopy system. A fully automatic extraction method is proposed which is significantly enhanced from current distance mapping method. The new approach consists of four steps: preprocessing; construction of improved Distance From Boundary field; centerline extraction ...

A monocentric centerline extraction method for ring-like blood vessels
Medical & Biological Engineering & Computing, 2017Centerline is generally used to measure topological and morphological parameters of blood vessels, which is pivotal for the quantitative analysis of vascular diseases. However, previous centerline extraction methods have two drawbacks on complex blood vessels, represented as the failure on ring-like structures and the existing of multi-voxel width.
