We tried to find any factor to reduce the exposure dose with ST-VA type generator which has the higher exposure dose. The guideline recommended by the provisions of IAEA regulation is being used at the time of radiation exposure and almost of those equipments used for this study had less amount of doses than those in the guideline. The FCR may be possible to decrease a certain amount of dose with effective applications of ifs automatic image compensation utillities and the verifying function in PACS. Next time, it is required to add a great number of hospitals for wide range of studies and measurements, and make standard exposure control table which will bing in practice, material decrease of dose volumes when radiation exposure.
