Abstract
The number of the people who died because of the cerebrovascular disease is 118,347, which is 9.3% of the total number of the people who died in 2014. Equipments utilized for medical treatment and inspection of the cerebrovascular disease include MRA (magnetic resonance angiography), CTA(Computed Tomography Angiography) and DSA(digital subtraction angiography) ,which can generate images of blood vessel. To precaution and detect early-stage disease, CTA and DSA cause the problem of radiation exposure and radiocontrast-induced renal failure. Thus, these method cannot be applied for these purpose. In contrast, MRA does not cause these kinds of problems and have no impact on human body. Therefore, MRA can play an important role for precaution and detection of early-stage disease. However, the strength of the signal of MRA highly could depend on the speed of blood. We make a research for the purpose that precaution of the cerebrovascular disease by utilizing MRA to analyze the 3D structure of blood vessel of the Internal Carotid Artery. For this purpose, the reconstruction of 3D models of blood vessels based on MRA data is necessary. The reconstruction of 3D blood vessel based on the threshold processing is difficult, because it highly depends on the speed of blood as previously mentioned. This paper reports the result of
comparison between MRA data and simulation of Internal Carotid Artery to make clear how to solve the problem of the dependency of the blood speed.
