Reading in .ima 3D image files from CBCT

I have 3D CBCT images to analyze but am not sure how to read in these image files. Each image consists of about 400 .ima files (which I am assuming are 2D slices that together form the 3D image). I am able to read in each individual .ima file, but I am not sure how to concatenate these files in ITK code in order to form just one single 3D image to analyze.

You are most likely dealing with a DICOM series. Take a look at this example which converts DICOM series into single 3D image files, which are easier to deal with.
