A sinusoid is a small blood vessel similar to a capillary but with a fenestrated endothelium. The arterial system The blood vessels are part of the circulatory system and function to transport blood throughout the body. ... Capillaries are the smallest of a bodys blood vessels, measuring 5-10 Î¼m. ... The endothelium is the layer of thin, flat cells that lines the interior surface of blood vessels, forming an interface between circulating blood in the lumen and the rest of the vessel wall. ...
Sinusoids are found in the liver, the bone marrow, lymphoid tissue, and endocrine organs. They are equipped with Kupffer cells that move and destroy any infections or bacteria entering the sinusoids. bhenchod The liver is one of the largest internal organs of the human body. ... Grays Anatomy illustration of cells in bone marrow. ... In mammals including humans, the lymphatic vessels (or lymphatics) are a network of thin tubes that branch, like blood vessels, into tissues throughout the body. ... The endocrine system is a control system of ductless endocrine glands that secrete chemical messengers called hormones that circulate within the body via the bloodstream to affect distant organs. ... Kupffer cells are reticulendothelial cells located in the liver. ... An infection is the detrimental colonization of a host organism by a foreign species. ...

Therefore, the presence of a 3D vessel segment may be detected by exploiting the recognition that from the perspective of an X-ray scanner, the vessel segments may appear as a succession of ellipses each having a characteristic density distribution (e.g., the density distribution described in equation 2).
A sinusoidal trace characteristic of a vessel may generate numerous detected ridge points, for example, a sinusoid of ridge points that track substantially along the center of the trace (e.g., each of the lightest pixels in profile 765 along the sinusoidal trace visible in sinogram 800).
Since each characteristic sinusoidal trace is assumed to be generated by a corresponding vessel cross-section, the ridge point (i.e., the peak of the Gaussian distribution) corresponds to the center of the elliptical cross-section.
