Hey everyone!
Pretty new to Slicer, but I’m currently using it to segment a section of the aortic root so that the cusps of the aortic valve and the calcifications are clearly visible.
I used the “Grow from seeds” method to segment the aorta and the the calcified portions and then subsequently rendered the aorta hollow so that a “scissor” operation across it could reveal the valvular commisures.
I’m however having some difficulties with this as I’m unable to smoothen and render the valve correctly.
My current model looks fine for the most part with the exception of the aortic root area where the valve (my region of interest) is.
My goal is to create a model that looks somewhat like the result shown here:
Thank you for your interesting question and sorry that people have not responded to you too. I have a similar problem and cannot utilize 3D Slicer to segment the aortic valve properly, will you share your further experience if you could solve this problem? Many thanks in advance!
Thank you very much Andras for many of your problem-solving comments from which I have learned a lot. The problem is that there are several approaches for what I want to do, and all of them end up with serious errors. For example, I really want to segment aortic valve with each leaflet segmented differently. If I try to use SlicerHeart, it does not work with 3D slicer’s crosshair at all and as soon as I try to put the Valve Annulus Analisis’ Contour Points to locate the Aortic Annulus it terribly changes the focus and I cannot locate the second point correctly. (The same problem happens when using Cardiac’s Valve Segmentation tools.
If I give up using SlicerHeart and try to use regular 3D Slicer’s tools such as Segmentation Editor, as soon as I paint one of the leaflets, it cannot paint anyone of the 2 remaining leaflets. You have given a solution for this problem in a reply to another post mentioning this problem and your suggestion enables the painting again but it could ruin the previously segmented parts.
I don’t know why Paint stops painting after painting the first cusp nor could use SlicerHeart’s Valve Annulus Analyzer & Valve Segmentation because of these problems.
