Variable slice thickness CT reconstruction

Hi,

I have slice images that I can process and interpolate and reconstruct the 3d image. My current analysis assumes that the thickness between slices are equal but in reality they are different. I have the individual thickness measurements.

This will change the final result due to the different interpolation distances. Has anyone dealt with this problem?

Thanks

I haven't dealt with this problem, but you could use interp3 or griddata3 to make the slices uniform.

==============

You could even use interp1, since you woul be interpolating only along one dimension (slices).
