    "abstract": "We present a tomographic scheme, based on spacetime symmetries, for the\nreconstruction of the internal degrees of freedom of a Dirac spinor. We discuss\nthe circumstances under which the tomographic group can be taken as SU(2), and\nhow this crucially depends on the choice of the gamma matrix representation. A\ntomographic reconstruction process based on discrete rotations is considered,\nas well as a continuous alternative.",
