Features of 1.2 µm size can be resolved with the imaging camera setup. (a) High-resolution radiographic projection of a Siemens star (collected with monochromatic beam at 15 keV); the red circle highlights a radius of 12 µm around the Siemens star centre for pixel intensity measurement. (b) Pixel intensity along the red circle, with ∼8% difference between high- and low-contrast regions. |
