We describe a phantom for simultaneous electroencephalography (EEG) and near-infrared
imaging which consists of a solid, optically turbid and electrically conducting
interface enclosing a tissue-mimicking aqueous scattering solution. The
interface provides an electrical contact impedance comparable to that of the
human scalp while the phantom as a whole has optical properties and electrical
conductivity equivalent to that of head tissue. The construction is described
and our design is evaluated experimentally using an optically absorbing target
which also provides an EEG-equivalent electric field source. The results of
this simultaneous EEG and near-infrared imaging experiment are presented.
