I read a text that shows valve building and uses a valve mold generator module. But i can’t find that module. I’m trying to start a research in my institution in brazil with 3d printed valves filled with silicone. Where i can find this module? Can you help anyway?
Some parts of the workflow (importing 4D US image, define annulus contour, segment leaflets, generate 3D-printable mold) are not yet publicly released. Do you already have a solution for segmenting the valve leaflets from images or you are building the complete workflow from scratch? Do you plan to do other cardiac simulation or analysis?
I 'm already segmenting valves using traditional tools and other cardiac structures too. My main project is to plan mitral valve surgery but i have other projects that i plan to use molds. My workflow is being built from scratch…
I plan to use other cardiac structures… any solution or advice?
How do you segment the leaflets? What software, what segmentation tools?
What is the result of your segmentation: 3D segmentation (closed surface or binary labelmap representation) or the leaflet surface (open surface)?
I’m doing all manually… using segment editor and separating leaflets using different color maps. It’s not so easy but works. Actually I’m printing in PLA and flexible filaments but I think silicone mimics better the tissue.
If you want i can send one segmentation I’ve done so you can give me some advice.
Currently, the leaflet mold generator module requires a leaflet surface (proximal surface of the segmented leaflet) as input, which is generated from the segmentation node using a tool that is not yet publicly released. We hope that we can publish it in SlicerHeart extension within a couple of months. While the module is convenient because it can create a mold fully automatically, including add labels, breathing holes, etc., with a bit of extra effort, you can do this operations manually, too - using Segment editor.
For now, you can create a mold manually by creating a “box” segment and subtracting all the leaflet segments. Then cut the mold into two segments using Scissors or other effects. You can make breathing holes in the top segment using scissors effect.
Thanks for the tips. I look forward to seeing the module active for the general public. Until then I will continue to work manually. In fact this helps me to get used to the software. I hope i can get the results i expect soon…
I’m having troubles when creating box in some models when the volume is too small. How can i enhance the extent of the volume?
You can change extent and resolution of a volume using Crop volume module.
Thanks. Please tell us when the leaflet mold generator module is ready to public.
