Outline of Final Research Achievements

The purpose of this study was to investigate the evaluation method for oral function using 320-ADCT. We investigated the effect of the latest dose reduction system. We used a tube voltage of 120 kV and a tube current of 40 mA and performed a dynamic volume scan for a period of 3.3 s. The result for the effective dose was 1.08mSv. The oral function CT examination with double contrast method conditions is tube voltage of 120 kV and a tube current of 10 mA and performed a dynamic volume scan for a period of 9.9 s. The result for the effective dose was 1.5mSv. The results obtained in this study would become the useful information when we reconsidered the radioprotection and the optimization of oral function CT examinations.
