Hi all, I am trying to extract the radius along a vessel, using its centerline. That is, to get the maximum inscribed sphere radius for each point along the centerline.
Following the discussion at: https://sourceforge.net/mailarchive/message.php?msg_id=21964561 I have managed to extract a *.dat file describing the X/Y/Z of each point and its associated radius. This was alright for a single vessel with no bifurcations. The new problem I'm facing is to extract the radius for a vessel that splits. I would like to get the radius along each branch separately. I have started by extracting the branches of the centerline (using vmtkbranchextractor) and then merging them using vmtkcenterlinemerge. In this process I have followed the discussion at: https://sourceforge.net/mailarchive/message.php?msg_id=22171493 When I save the file as *.dat (vmtksurfacewriter -ifile CT_merged_centerline.vtp -ofile mergedRadius.dat), I get the points and associated radius but don't know to which branch they belong to. So now I'm trying to export it as *.vtk : vmtksurfacewriter -ifile CT_merged_centerline.vtp -ofile mergedRadius.vtk When I open mergedRadius.vtk (attached) in a text editor, I see the following line: LINES 3 123 I assume this means the following: - There are 3 lines, with a total of 123 points in them - The values following this line correspond to the center-points indices - The indices are separated into 3 groups by a new-line character. Each group includes all points of a single branch Are these assumptions correct? If not, how can I associate the maximum inscribed sphere to a specific branch in an orderly manner? Thanks, Ido
