Exit wave reconstruction and PSNR of simulated apoferritin data with different numbers of tilted illumination images and varying fluence. (a1)-(a4), (b1)-(b4), (c1)-(c4) and (d1)-(d4), reconstructed phase and calculated PSNR values from datasets with different total fluence and total number of tilted images. All images use the same scale bar as (a1). The phase scale bar is in radians. Odd numbers for the total tilts include one axial illumination image.
