Re: Errror in Segmentation @ Multi vessel path using Machine learning

Hi Sabush,

Thanks this was helpful.

What version of windows are you using and how much RAM do you have?

Re: Errror in Segmentation @ Multi vessel path using Machine learning

Thanks for the quick response, Importing an image through Open File is currently not supported. Could you try importing the image by right-clicking on "Images" in the data manager on the left side of the screen and then choosing "Add/Replace images" to import your image? You can also see how it is d...

Re: Errror in Segmentation @ Multi vessel path using Machine learning

Hi Subash, Thanks for reaching out. To help could you answer a few questions? What image format are you using (e.g. MHA, DICOM, VTI etc.)? How are you loading the image into SimVascular? If possible could you also try launching SimVascular from a command window and then reporting any error messages ...

Re: Automatic Machine learning confusion

Hi Chyna,

Thanks for posting your issue.

Have you tried closing and reopening the 2D segmentation plugin? If the plugin is open when you load a project it will not read the paths, so you need to refresh it by closing/opening.

Re: 3D colliding fronts segmentation in branches

Yes, if you create individual 3D segmentations for each vessel, you can then merge them together in the modeling part of SimVascular. It is a bit unclear what is going on with the segmentations in your picture. Are you saying that they do not appear in the axial/sagittal/coronal planes? Or are they ...

Re: Machine Learning Algorithm is Not Capturing Vessel Walls

Hi Frank,

I believe the resizing may be the issue. How exactly are you resizing and by how much?

Re: 3D colliding fronts segmentation in branches

Hi Lisa,

The colliding fronts algorithm will compute separate vector fields for each start/end seed combination and then union the resulting vessel models.

In your case one start seed with two end seeds should work.

Best,

Gabriel

Re: SimVascular Crashes during ML segmenting

Hi Srihari, Thanks for letting us know about this. Could you let me know the following information: * What kind of image data are you using? * What file format is the image? * How are you loading in the image? Then could you also let me know * What operating system are using? * What version of SimVa...

Re: Issues with SimVascular compilation from source on Linux

Hi Emilie, What distribution and version of linux are you building on? We have precompiled versions of all the externals which are normally downloaded when building SimVascular, usually this works fine and is the recommended process. Is there a particular reason you want to build everything from sou...

Re: Centerlines and re-slicing

Hi Marcela, Unfortunately you can't export the image reslices directly from within simvascular. If you have the centerline points, you could try Paraview and using one of their slice options, e.g. "slice along plane". Alternatively if you want to do it programmatically you could access VTK's reslice...
