Volume rendering and multiplanar reconstruction

[mikebind (Mike Bindschadler)]

Are you creating the DICOM headers yourself? Slicer does not use the “Slice Thickness” to set the slice spacing, see discussion here:

@pieper

The out of plane spacing is defined by the distance between the ImagePositionPatient of adjacent slices, not by the SliceThickness, which can be different for a variety of reasons.
