My overall goal is to 3D print a realistic aorta phantom that can reproduce the same flow rate as blood flow. To do this, I have segmented a real aorta from MRI images. Now, I need to modify the radius, or the length (or a combination of both) of each branch of the aorta to very specific values (which I have calculated using a biomedical engineering model). If I don’t do that, the model will look like a real aorta but it won’t reproduce the same flow rate as blood flow.
Therefore, I need to:
-
Know how long each branch is (I was able to find the length of each branch using the centerline extraction so this has been solved already) and to Shorten or extend each branch to a specific length ( while retaining the morphology of my model as much as possible).
-
Know what the radius (or diameter) of each branch is and find a way to modify it (in a way that retains the morphology of my model as much as possible).
-
The margin tool looks like it will do the trick to change the radius of each branch, but I still need to find out what the numbers are (maybe using the python code you told me about).
-
I still don’t know how I can extend or shorten the branches of my model… I thought it would be possible to link the center lines to my blood pool (solid) model, such that the length of each branch of my blood pool model could be changed by extending or shortening the center line branches. I also thought that the radius of my blood pool branches could be changed in a similar way.
