Hi

I am trying to reconstruct 3d heart model from cineMRI data. I have followed the steps from " Reconstruct 4D volume from cine-MRI frames".  
now I have 5 volume sequence exported in .NRRD format

1. AOT trufi cine - 25 frames volume sequnce by InstanceNumber
2. 4 CH trufi cine - 25 frames volume sequnce by InstanceNumber
3. 3 CH trufi cine - 25 frames volume sequnce by InstanceNumber
4. 2 CH trufi cine - 25 frames volume sequnce by InstanceNumber
5. SAX trufi cine - 25 frames volume sequnce by InstanceNumber

I have to reconstruct 3d heart model so how should I proceed further.  
How I can create one sequence volume for further segmentation at each time frame

Thank You

Hi

can anyone help me to build single sequence volume for model segmentation from 5 time series mentioned in above post.

I am struck at this point. How to generate single volume for segmentation from the above 5 volume sequences. Please guide me further
