Fig. 3From: Ring stage classification of Babesia microti and Plasmodium falciparum using optical diffraction 3D tomographic techniqueThree-dimensional refractive index maps of uninfected RBCs and ring stage of B. mictori and P. falciparum. The cross-sectional image shows the middle focus of x, y plane ± 0.6 um of A uninfected RBCs, B B. microti- and C P. falciparum-infected RBCs of section image. The color density map indicates the refractive index (RI, n) and the hemoglobin concentration (g/dl)Back to article page
