Siemens AG b45f reconstruction
Example sections of a scan reconstructed with two kernels in the Siemens scanner with an emphysema overlay highlighting voxels below -950HU. The upper row shows the original sections reconstructed with ( A ) b31f and ( B ) <t>b45f</t> kernels. The lower row shows the same sections after normalization with ( C ) b31f and ( D ) b45f kernels. The ES obtained for the ( A ) b31f original scan was 9.5 %, for the ( B ) b45f original, ES was 21.2 %, whereas for the ( C ) b31f normalized, ES was 10.1 % and for the ( D ) b45f normalized, ES was 10.9 %

Article Snippet: The second mixed cohort (n = 369) was constructed to contain scans with both standard and sharp kernels from both manufacturers: from the Siemens group, the b31f reconstruction was chosen for 92 randomly selected subjects, and the b45f reconstruction for the remaining 91 subjects.

Techniques:

Bland-Altman plots comparing ES values for (A) original b31f and original b45f, and (B) normalized b31f and normalized b45f in the Siemens group. The mean differences are shown with a solid line ; the limits of agreement are shown with dashed lines

Techniques:

Correlation of ES measured for the three groups (Siemens, GE and Mixed), for each cohort, before and after normalization
