Low dose reconstruction. (a) Schematic drawing of the beam positions: red filled circles used, gray filled circles skipped. (b) ITR phase images of the same area reconstructed with various electron doses (based on dataset with 20 nm defocus). The results show significant reduction in sample structure visibility with decreasing electron dose, where Boron atom columns can be still recognised down to dose of 530 e/Å\(^{2}\) but at 231 e/Å\(^{2}\) it is very difficult to distinguish both, Samarium and Boron atoms from background. Bars correspond to 5 Å.
