Figure 2

Mean density curves and AUC(CV _T ) distributions. (a) The mean density curves of the 40 noise realisations of the CV values for the imaged healthy distribution (black line) and imaged COPD activity distribution (grey line) for the top-ranked LEHR-125 MBq design in Table 5 (a kernel edge length of 2.3 cm, six iterations (96 updates) and a cutoff frequency of 0.7 cm⁻¹). (b) Histograms of the AUC(CV_T) values of the 40 noise realisations for each activity distribution. (c) The same information as in (b) but visualised as mean values with 95% confidence intervals. Data are for the reduced lung.
