1) To outline basic principles of CT radiation exposure and its quantities 2) To summarize CT radiation dose optimization based on modification of scanning parameters and application of technologic innovations 3) To demonstrate optimal strategies using current and novel technologies by presenting experimental data and clinical images  

1) CT radiation dose quantities ・ CT dose index (CTDI) ・ dose length product (DLP) ・ effective dose (ED) ・ size-specific dose estimates (SSDE) 2) scanning parameters and technologic innovations ・ CT system optimization: detector/collimators/beam-shaping filter ・ automatic exposure control ・ optimal tube potential ・ noise control in reconstruction and data processing ・ dual energy CT 3) Optimal strategies for dose reduction ・ appropriate indications ・ optimal scan length and phases ・ use optimal scanning techniques ・ provide optimal protection
