Summary of the statistical analysis performed on the breast dose data for adult patient models in mGy. Graphs (a) and (c) are the scatter plots for each method, while (b) and (d) are Bland-Altman graphs showing mean and standard deviation of the breast dose (mGy). The x axis of the scatter plot shows doses in mGy from detailed TCM function (X1) and the y axis represents doses in mGy from either the longitudinal approximated TCM or fixed tube current (X2). The x axis of the Bland-Altman graphs is (X1+X2)/2 and the y axis represents (X2-X1). For both methods the means are very close to the y = 0 lines, however, the standard deviation is larger for the fixed tube current method compared to the longitudinal approximated TCM method.
