a) MTF curve for the DDD at 300 keV calculated using the fitted curve in Figure 2. The finite pixel size effect has been corrected using a sinc function. At ½ Nyquist frequency (50 lp/mm), the MTF of the DDD is >12%. The DDD clearly outperforms other detectors at the same spatial frequencies.

b) The same MTF curves but shown using the usual scale of 1/pixel. The Nyquist frequency for any detector is now at 0.5/pixel and ½ Nyquist frequency is at 0.25/pixel. A detailed tabulated comparison is given in Table 1.
