Re: Trying to add different stenosis degrees to model

Thanks both, Erica I will have a look at your script this afternoon. I know of that method david however, only with a circle would this work due to the fact that I want to be precise with my diameter so interactively sliding and changing will not really work, since I won't know which diamtere it is....

Trying to add different stenosis degrees to model

Hello all, I have the following question: I have MRI images from AV graft patients, and with SimVascular I have created a model of the venous anastomosis + part of the vein and part of the graft. The model can be seen in the attachment. Now I am longitudinally following these patients up with ultras...

.vtp converter?

Hi everyoe, Does anyone know of a .vtp file converter. I have reached the point that I have the model in SimVascular, however I now want to export the model to be able to use it in other software (SolidWorks, Ansys ICEM) and they do not take .vtp files but only other formats. Has anyone else also ne...

Re: Bad quality images!? SimVascular inefficient image loading?

Ah okay that could explain it, the resolution was 0.8 x 0.8 mm I think but obtained Saggital.

Bad quality images!? SimVascular inefficient image loading?

Hello, It has appeared to me (although I am not completely sure) that whenever I load MRI Dicom files into SimVascular, they seem much more pixelated compared to the software in the hospital / other software like RadiAnt. In SimVascular it always seems to be of lesser quality. Attached I have put 2 ...

Segmentation Question ; automatic segmentation difficulties.

Hello, Ik trying to segmentate an Arterial Venous Graft and the corresponding vein and artery it's connected to. Whilst testing some other images, the LevelSet option worked for me and I was able to automatically let Simvascular sementate my images through the planned path. Now, however it keeps sel...

Classic DICOM vs Enhanced DICOM; failing to load in images to project

Hello, Previously I was able to easily add my DICOM files to my project. These were exported to me as basic DICOM files (so each image would consist of a folder of multiple dicom files). Now I have recieved images exported to me as Enhanced DICOM files , 1 image corresponds with 1 large DICOM file. ...

Re: Difficulties with segmentation

Hi David,

I could send you the data, but yesterday I've discussed a new protocol for the image acquisition with the MR fysician and it allready seemed much better, so I'll wait for the next patient and try it with the new data.

Cheers,
Jack

Re: Difficulties with segmentation

Hello David,

I have just talked to the MR clinical physician, and we are going to test if 3D isometric images will give better resolution in the axial plane. Hopefully this will resolve some of the issues.
Cheers Jack
