3D Interpolation

Hi,

i want to match two 3D-medical-image-dataset with different resolution.
To obtain the same resolution i have to interpolate the dataset with the
lower resolution.
One way to interpolate is the tri-linear interpolation.



What is the best (fastes) way to do this ?

I am confused about the way to implement such an algorithm ?

One way is to set up 8 equations
(F(x,y,z) = a + b*x + c*y + d*z + e*xy + f*xz + g*yz + h*xyz)
with the value of the 8 neighbouring voxels and to solve this
equation-system with gaussian elimination.

Or is it possible to perform the 3D-interpolation by convolution
(Fourier Transformation).

Does anyone know some papers or www-pages about the theme
3D-interpolation.


If so please send an email to me.
Christian.
