Abstract
The purpose of this study is to reduce the dose to the patient by different application of ASIR according to the Body Mass Index (BMI). In particular, we wanted to find out the application values of ASIR that are most appropriate for the standard weight. Studies have shown that increasing the application of ASIR to 50% in patients with a body mass index of 25 or less reduces CTDIvol 58.17% and DLP 60.49% compared to using only FBP. A comparative analysis of the noise by the BMI and the SNR values found that the noise increased as the BMI increased, but the application of ASIR resulted in less noise than the FBP alone. In addition, it was found that the more ASIR is applied, the more SNR is increased.
