A clear digital image of blood vessels by using a CT angiography or MR angiography is easily obtained in medical field. Recently, the disease by arteriosclerosis increases rapidly. Especially, the one that originates in hands and feet's peripheral arterial is called arteriosclerosis obliterans (ASO). To diagnose the ASO using a magnetic resonance imaging (MRI) applied as a useful visual screening method on the medical field. To avoid adverse reactions from the contrast medium non-enhanced fresh blood imaging (FBI) method is developed. In this paper, we develop a 3-D visualization method for analyzing the internal structure such as blood vessels in the lower limbs area. To develop a visualization method, we propose a technique for extracting the blood vessels region by use of region growing method which obtained the MIP image. This technique was applied to four non-enhanced FBI MR imaging, and satisfactory 3D blood vessel region was extracted. Some experimental results are shown with discussion.
