I have 200 2D images (slices) which represent a volume of a blood vessel (basically, a tube). The pixel size in each of the 2D images is 5 microns and the distance between the slices is 200 microns. How can I add slices such that, when viewing the volume, the voxels are approximately square (i.e. how to I add 40 new slices between each pair of the original slices?).

Thank you

If the data you have is a scalar volume or labelmap volume then you can resample it in the Crop Volumes module.  
What format is the file(s) you load into Slicer?

I have it in a single file as stacked tiff. I separated the stacked tiff and saved the separate images in order to load into 3D Slicer.
