This is a wrapper around the basic nifti_image (stored as a sptr), with extra functionality.

This is the general form, and any number of dimensions are allowed. This is contrary to the derived classes, which have specific requirements (e.g., NiftiImageData3DDeformation requires 5 dimensions, of which the 4th (time) == 1).

To move between different images types (e.g., STIRImageData and MRImageData), we need to know the patient's position relative to the scanner. For this, only qform_code == 1 will suffice.

qform/sform The qform code describes "scanner-anatomical" coordinates, whereas the sform code describes the location of the voxels in some standard space.

For qform > 0, the origin of coordinates would generally be whatever the scanner origin is; for example, in MRI, (0,0,0) is the center of the gradient coil.

For sform > 0, the origin of coordinates would depend on the value of sform_code; for example, for the Talairach coordinate system, (0,0,0) corresponds to the Anterior Commissure.
