Iam working with CTA volume having dimensions 512*512*304. How I can convert the volume into isotropic form having axial size of 256*256.I have gone through http://stackoverflow.com/questions/32018133/converting-non-isotropic-to-isotropic-voxel but it didnt help me .
Iam not sure how to proceed but still i have read necessary parameters (may be required for above problem)from dicom including spacing between slices=0.45 AND pixel spacing is 0.4 for both x & y.
One more question I want to ask is about transformation into world coordinates. When I am working with original volume(512*512*304), The extracted tube is identical in shape to the reference data , but in terms of coordinates position, it shows a notable difference. My colleague asked me that reference data is in world coordinate.
Many thanks in advance;

correct me if wrong but you want to basically transform a non isotropic voxel volume into an isotropic voxel volume, as detailed in SIEMENS presentation, pg29
In another link:
Dirk-Jan Kroon has posted a DTI and Fiber Tracking toolbox that has a function called
plot3t
Is this the function you are after, or the inverse of plot3t?
If you are trying to go from one standard file format to another one, would you please detail the formats among the following list?
the free viewer RadiAnt
exports directly to .jpg and .wmv
Please let me know if the non-isotropic to isotropic transform your are looking is performed by any of the above. thanks in advance
John
