adds up to roughly 90 microsieverts. A 3D dose is
roughly half that. With partial rotation, low settings,
and pulse technology, CBCT can now be taken with
less radiation than a panoramic radiograph. "For
orthodontics, I don't need a 100-micron voxel size full
field of view scan," said Dr. Burton. "Most of my scans
are taken at 600 microns, which is perfectly acceptable
for orthodontic diagnostics, so [with 3D], I can have all
the information I need with significantly less radiation

* Gain more accurate measurements
* Improve localization
