Using Hilbert phase microscopy for extracting quantitative phase images, we measured the average refractive index associated with live cells in culture. Tb decouple the contributions to the phase signal from the cell refractive index and thickness, we confined the cells in microchannels. The results are confirmed by comparison with measurements of spherical cells in suspension.
