Combined visible light optical coherence microscopy and fluorescence imaging setup to investigate 5-aminolevulinic acid postive glioma samples.

5-aminolevulinic acid positive brain tumor samples were investigated with a multimodal visible light optical coherence microscope (OCM) and fluorescence imaging (FI) setup. Tumor specific contrast was achieved by the FI part while the three-dimensional tissue morphology was assessed by the OCM part of the setup.
