A member asked:
Could you tell me the difference in the radiation units you get between head ct vs. cbct?
A doctor has provided 1 answer
Very variable: As a whole, the conebeam ct units delivered a lower dose than the multi detector ct units. However, there were very wide variations in the doses delivered to different sites and differences in imaging technique and between different units from different manufacturers! the very technical article is here: http://www.Sitech.Fr/telechargement/ludlow_jui_08.Pdf not a light bedtime read!
