[SciPy-User] ndimage.sobel multiple passes?

In my code base, currently I need to compute sobel on a 3d dataset. I do
this using:

# ndimage.sobel
    dx = sobel(vdata, 0)
    dy = sobel(vdata, 1)
    dz = sobel(vdata, 2)

any ideas how this can be done using one pass instead of doing this in 3
passes. My dataset is large and it would be nice to speed this up.

Thanks,
--R
