QPI results of unlabeled HeLa cells. (a) Approximately 4000 HeLa cells on a ∼7.19  mm2 FOV. (b1) and (c1) Low-resolution brightfield (BF) in-focus intensity images of areas 1 and 2 in (a), respectively. (b2) and (c2) Low-resolution darkfield (DF) in-focus intensity images of (b1) and (c1), respectively. (b3) and (c3) Retrieval phase results of (b1) and (c1) using the FFT-based traditional transport of intensity equation (TIE) phase retrieval method, respectively. (b4) and (c4) Retrieval phase results of (b1) and (c1) utilizing the novel HBDTI method, respectively.
