Abstract
We demonstrate high-resolution (3.8-µm axial and 4.8-µm lateral) three-dimensional dynamic (D-) OCT imaging by 840-nm spectral domain OCT, and compare it with a low-resolution 1.3-µm D-OCT. The D-OCT images are obtained by logarithmic-intensity-variance method, which is sensitive to the magnitude of signal fluctuation. Human-induced-pluripotent-stem-cell derived alveolar (lung) organoids and human breast cancer (MCF-7) spheroids were examined. The high-resolution D-OCT revealed the tessellation of high and low dynamics at the matured alveolar epithelium. It is also found that such matured alveolar epithelium exhibits ragged inner surface. For the spheroids, high-scattering spots with low dynamics were observed only in the high-resolution image.
