Abstract
We utilized a visible light optical coherence microscopy imaging (OCM) system to investigate the intra-tumor heterogeneity of glioblastoma samples. Using a broad visible spectrum an axial resolution of 0.8 μm was achieved. Objective lenses with short focal lengths were integrated to achieve high transverse resolution. Large field of view images were acquired using an automatic moving x-y-stage. Attenuation maps were calculated from OCM data and cell-density evaluations were performed from corresponding histological sections. Cell density and attenuation data were evaluated. Our analysis revealed intra-tumor heterogeneity by varying cell densities and attenuation coefficients throughout the tumorous areas.
