The geologic structure can be imaged from the refracted/reflected waves. In theatrical use, a proprietary 24-bit time code is optically imaged onto the film. The beam deflection can then be imaged on a segmented or pixelated detector. Targets can be reliably imaged through the application of multiple short singly labeled oligonucleotide probes. The Hawaii hotspot has been imaged through seismic tomography, and is estimated to be wide. Most of the hemisphere not imaged by was mapped during these fly-bys. They also remotely imaged the surface and search for interplanetary dust around the asteroid. Fluorescein-labelled probes can be imaged using FISH, or targeted by antibodies using immunohistochemistry. After being laminated to the PWB surface it is imaged and developed as LPI. Radio frequencies are transmitted at the Larmor frequency of the nuclide to be imaged. This allows such sites to be imaged by nuclear scan techniques. Presently, only the head and brain can be imaged at these high magnetic field strengths. With this resolution, individual atoms within materials are routinely imaged and manipulated. Rhea has been also imaged many times from long to moderate distances by the orbiter. Iron tablets may be imaged by radiography.
