Advanced Visualization Techniques for Vessel Investigation
Different approaches of visualization techniques and segmentation methods for computed tomograpy angiography datasets are investigated. The particular characteristics of this data are addressed. A global path-optimisation method for a reliability-enhanced vessel-tracking method was introduced. Furthermore an interactive segmentation technique focusing on the clinical use is proposed.
متن کاملVessel Extractio Techniques and Algorithms: A Surve
Vessel segmentation algorithms are critical components of circulatory blood vessel analysis systems. We present a survey of vessel extraction techniques and algorithms, putting the various approaches and techniques in perspective by means of a classification of the existing research. While we target mainly the extraction of blood vessels, neurosvascular structure in particular, we also review s...
متن کاملReproducibility of coronary vessel wall imaging techniques
Background Coronary wall thickness measurements must be highly reproducible to be useful in longitudinal studies. While 2D turbo-spin-echo (TSE) and spiral techniques are commonly used, 3D techniques reduce partial-volume effects and allow greater vessel coverage. Recently, 3D coronary wall imaging was demonstrated with 100% respiratory efficiency (RE) using beat-to-beat respiratory motion corr...
متن کاملQuantitative evaluation of vessel tracking techniques on coronary angiograms.
Accurate, automated determination of vessel center lines is essential for two- and three-dimensional analysis of the coronary vascular tree. Therefore, we have been developing techniques for vessel tracking and for evaluating their accuracy and precision in clinical images. After points in vessels are manually indicated, the vessels are tracked automatically by means of a modified sector-search...
متن کاملSegmentation and Reconstruction Techniques for Modeling of Blood Vessel
Vascular diseases are nowadays one of the serious issues which have a huge impact on someone's life. Number of researchers at different universities as well as medical device manufacturers are working in this field for better understanding of the vascular characteristics. It is expected that three dimensional structure of blood vessels can provide comprehensive visualization of vessel geometry....
