Fig. 3: The density profiles retrieved from the measured refraction-enhanced radiograph (RER) intensities using a deep neural network.


a Shows the RER intensity lineouts and b Shows the retrieved density profiles. The red dashed curves are calculated intensity lineouts from the densities. The CH/Be interface is located at r = 1000 μm. The corresponding time delays are labeled as unheated, 2.1, 2.8, 4.1, 6.1, and 6.8 ns.
