Study demonstrates variations in effective dose calculation based on phantom sizes and scan parameters, indicating important determinants.
Our study demonstrated the large variations of DLP-normalized effective dose. Standardized coefficients revealed that patient weight, height and/or scan length were the most crucial determinants. Depending on the specific TCM model used, even greater variations may be observed. This work also provided a practical framework for estimating CT effective dose using the traditional k-factor method with updated new conversion factors.
