Before Change

    
    Convert an ANTsImage to a Nibabel image
    
    if image.dimension != 3:
        raise ValueError("Only 3D images currently supported")

    import nibabel as nib

    array_data = image.numpy()
    affine = np.hstack(
        [
            np.matmul(image.direction, np.diag(image.spacing)),
            np.array(image.origin).reshape(3, 1),
        ]
    )
    affine = np.vstack([affine, np.array([0, 0, 0, 1.0])])
    affine[:2, :] *= -1
    new_img = nib.Nifti1Image(array_data, affine)
    return new_img

After Change

    import nibabel as nib
    tmpfile = mktemp(suffix=".nii.gz")
    image.to_filename(tmpfile)
    new_img = nib.load(tmpfile)
    // os.remove(tmpfile) //// Don"t remove tmpfile as nibabel lazy loads the data.
    return new_img
