<div dir="ltr"><div><div>Dear Jeanita,<br><br></div>What do you mean with "get the
vessel lumen"? What kind of output do you expect? If you have a 3D
centerline from a series of descriptors (2D points and radii) you could
easily obtain a new set of interpolated sections across the 3D
centerline with the desired sampling factor for the distance along the
centerline, by simply interpolating the center and radii. From this you
could generate a somehow smooth 3D surface model by sweeping those
sections, you could do this easily with VTK, i think i did it once.<br><br>If
want you want is a voxel-based segmentation of your lumen this is far
more difficult, but I dont know to which extent is useful, because your
source data is by nature sparse, and you will try to fill an entire
dense volume, with the necessary memory and computation resources, which
does not adapt to the nature of your source data.<br></div><div><br></div><div>Hope that helps<br><br></div>Iván<div><div><div><div class="gmail_extra"><br><div class="gmail_quote">2013/10/9 jeanita frank <span dir="ltr"><<a href="mailto:jeanita.frank@gmail.com" target="_blank">jeanita.frank@gmail.com</a>></span><br>

I extracted the 2D centerline and radii and I obtained the 3D vessel centerline by strereoscopic reconstruction but I don't have any idea on how to get the vessel lumen from cross sections. <br>
Can someone help me please.<br></div>
