[Insight-developers] Tool for converting 2D images to 3D volume

[Bradley Lowekamp]

Hello,

If you feel like passing your arguments in a scripting language as opposed to the command line then SimpleITK would be an excellent chose for this.

There are pre-compiled built distributions for Python, Java and  C#, while if R, Tcl, or ruby is preferred you will need to compile from source. More information can be found on the wiki about getting started:

http://www.itk.org/Wiki/ITK_Release_4/SimpleITK/GettingStarted

I don't specifically know what you need to do, but it likely can just be done in a couple lines of Python. I don't have an example to point you too, but as this is a common task, I could do that if it would be helpful.

Briefly something like this should work:

fnames = glob.glob("my*.ext")
img = sitk.ReadImage(fnames)
img.SetSpacing( [1,2,3] )
sitk.WriteImage( "out.mha", img )

I found quite some threads and also a guy posting what seemed to be exactly what I was looking for https://sites.google.com/site/pierrefillard/coding-blog/createa3dvolumefromseveral2dimages. In fact, I was amazed and extremely happy; sadly, the SVN URL provided on the website doesn't work, for whatever reason.

The program presented in the link above was actually really cool, for the fact that it could also convert 3D images to 4D ones.
