construct 3D volume from three orientatio​n(Axial,co​ronal,sagi​ttal) acquired volumes

Dear all,

I am looking method for interpolation of 3 Different orientation volumes(Axial,coronal and sagittal MRI's) to construct 3D volume.

[Matt J]

Aren't the axial, coronal, and sagittal data sets just alternative partitionings of the exact same volume? Why not just apply interp3 to the axial data set and throw the others away? What informaiton is there in the coronal and sagittal data sets that is not contained in the axial data set alone?

Each Axial,Coronal and Sagital MRI volume is 512*512*24 resolution. If we make use of all the orientation volumes can we reconstruct super resolution volume ?

Thank you for the reply.

warm regards,

I don't think so. Would you want the final volume to be 512x512x512? You only have 512*512*72 image samples, so I don't see how you could upsample to 512^3.

[divya B]

Can we reconstruct 3D volume from these 3 orientation(Axial,coronal and sagittal) MRI volume?

It already is a 3D volume. You need to decide what grid you want to sample to, or if you're okay with using the lower resolution in 1 direction.

Thank you for the support.

We have axial orientation volume with 512*512*24 resolution. But this in sagital orientation is 24* 512*512 and coronal orientation is 24*512*512 resolution ie, lower resolution. So i am looking for 3D reconstruction from seperately acquired Axial,coronal and sagittal MRI's.

Mainly looking for --- The resultant 3D reconstruction should have resolution similar to 3D acquisition MRI volume.

So Is this possible?

[Matt J]

The resultant 3D reconstruction should have resolution similar to 3D acquisition MRI volume.

We don't know what that means. You said you already have three 3D MRI volumes. I understand that they are not at the resolution that you want, but what resolution do you want?

[divya B]

Thank you for the support.

The resultant 3D reconstruction should have resolution similar to 3D acquisition MRI volume. -------> Means

I want to construct an isotropic volume of 1mm3 resolution considering all the acquired 3 orientation MRI volume.
