Towards true volumetric refractive index investigation in tomographic phase microscopy at cellular level - dataset

This dataset contains 6 files with reconstrucions of 3 different types of cells (SH-SY5Y neuroblastoma cells, A549 adenocarcinoma lung cells and HL-60 white blood cells), retrieved from optical diffraction tomography system measurements carried out at Warsaw University of Technology. The measurements were reconstructued with 2 different algorithms: direct inversion algorithm (DI) and Gerchberg-Papoulis algorithm with finite object support regularization (GPSC) [1]. 

All files are *.mat files.

In the files there are 5 variables:

REC - reconstruction matrix with information about 3D refractive index values in the cells
dx - sample size 
RI2D - values of mean refractive index calculated from 2D lateral cross-sections
RI3D - volumetric mean refractive index
mask - binary mask of the cell
