I don’t know how this relates to the topic title (template matching), but you can crop a volume using Crop volume module.

i would like to crop only one slice then I will use it as a template later in matching the same feature in other slices, sorry for confusing title

You’ll get inaccurate 3D alignment if you only use a single 2D slice for alignment of images.

You can fully automatically align two images of different patients (either rigidly or using warping transform) using SlicerElastix extension. _General registration (BRAINS)_ module that is bundled with Slicer may be usable, too, but usually it requires more parameter tweaking.

If you prefer not to do intensity-based registration then you can align images based on anatomical landmarks using _Landmark registration_ module or SlicerIGT extension’s _Fiducial registration wizard_ module.
