Enterprising technocrats can design a new imaging apparatus by utilizing the energy absorbing nature of nervous system. Infrared rays, microwaves or radio waves etc. of appropriate frequency and intensity may be emitted to the lower part of spinal column. Central nervous system (Brain + Spinal cord) shall absorb this energy through filum terminale and it shall be emitted from spinal cord and brain. By analyzing these emissions the image of spinal cord and brain can be got through the process similar to the process in Positron Emission Tomography (PET) and Single photon Emission Computed Tomography (SPECT). Advantage of the newer apparatus shall be that, it needs no radio isotopes to be injected into the body. This process shall be having less adverse effects. This apparatus may be named Electro Magneto Encephalogram (E.M.E.G)
