The image on the cover for Advanced Photonics Volume 2, Issue 2, demonstrates the three dimensional tomographic reconstruction of red blood cell using a deep neural network, which instantly provides high-fidelity reconstructions by solving the missing cone problem. The image is based on the research presented in the article, “Three-dimensional tomography of red blood cells using deep learning,” Adv. Phot. 2(2), 014003, doi: https://doi.org/10.1117/1.AP.2.2.026001.
