Hello,
I need to import 4D flow MRI data which is in DICOM format into Ensight, in order to get the flow rate of the artery at different locations. But I have no idea about both the data format and how to compute the flow.
Can anyone help with this please.

Many thanks,

Ming

you can not read dicom directly into ensight. 

please see following. 

Many users of EnSight with DICOM data from MRI use filtering algorithms run through Matlab. We have an external reader for "Analyze/NIfTI" format data which is commonly used for Neuroimaging MRI and PET. There are a LOT of converters out there to convert from DICOM to Analyze (standalone, matlab based, IDL based, etc):

There are pluggins for ImageJ which convert to NIfTI format :

So, users may need to use the NIfTI/Analyze format as the intermediate format between the raw output from the MRI scan and the data inside EnSight.

 

if this helps you, please mark this post as 'is solution' to help others on forum.

Hi,

I have already converted DICOM data into .nii format, but it seems that there are no velocity data in it. The only variable I've got is 'volume' as shown in the picture below, which is just a scalar.

Could you please tell me how to get velocities? Or should I need to use filtering algorithms through Matlab firstly?

Many thanks,

Ming

as there are third party, we can not guarantee. i have not used it myself. you may need to do some trial and error.
