Figure 4
Simulated percentage depth doses in 3 T mode with (a) Cu/Cu filtration, (b) Cu/Al filtration and (c) Al/Al filtration. The percentage depth doses in the absence of the transmission detectors (TDs) (black) are compared with the percentage depth doses downstream of the 10 µm thick (red) and 375 µm thick (blue) transmission detectors. The percentage differences between the response with and without the 10 µm thick (red) and 375 µm thick (blue) transmission detectors in front of the water phantom are presented below each percentage depth dose plot. |
