Figure 2

Cryo-electron ptychography reconstructions from simulated data and simulated cryo-EM images for different doses and 3 macromolecules with growing molecular weights in columns 1–3. Row (a) Phase of the transmission function, the ground truth for the ptychography reconstructions. The scale bar next to the figures is in rad. Rows (b) and (e) ptychography reconstruction at doses of 5 e 2 and 20 e 2. Rows (c) and (f) Simulated cryo-EM image with a defocus of 1.6 μm at a dose of 5 e 2 and 20 e 2. Rows (d) and (g) Simulated cryo-EM image with a Zernike phase plate and a defocus of 50 nm at doses of 5 e 2 and 20 e 2. Column (1) hemoglobin, column (2) 20S proteasome, column (3) human ribosome.
