Vessel Tracking Of Arteries And Veins In The Human Head And Neck

Nowadays,as the improvement of people's living standards,people also suffer different types disease,especially multiple sclerosis disease(MS).Research on nerves and blood vessels of the brain gradually deepened,so far no rigorous scientific decision is made in the pathogenesis of these diseases.Through a large number of cases,Researchers find poor blood flow that lead to high blood pressure may cause brain vascular bleeding;therefore,the vessel tracking of arteries and veins in the human brain and neck open the window of pathogenesis of these diseases.By accessing to relevant documents and trying abundant experiments,by two ways,based on magnetic resonance angiographic images to achieve the vein and artery detection,tracking and calculating the cross-sectional area of the vessel.By comparing the results,not only to verify the accuracy and advantages of dynamic programming algorithm;Stenosis study of these diseases provides greater clinical significance.This study is based on the magnetic resonance angiography to achieve the cross-sectional area of the vessel:VMTK and dynamic programming(DP)algorithm,VMTK get cross-sectional area of vessels,and it can be the reference,each slice of the image has a different cross-sectional area,resolution,and SNR.First verification the parameter of the image acquisition;obtaining a better magnetic resonance angiography(MRA)and achieving vascular detection,tracking,and calculate.Comparing the results,dynamic programming algorithm(DP)achieve accurate vessel stenosis measurement,automatic tracking,which provide a powerful scientific clinical tool in researching multiple sclerosis disease and so on.
