High speed 4D in-vivo OCT imaging of the human brain: Creating high density datasets for machine learning toward identification of malign tissue in real time

Neuro-surgery is challenged by the difficulties of determining brain tumor boundaries during excisions. Optical Coherence Tomography is investigated as an imaging modality for providing a viable contrast channel. Our MHz-OCT technology enables rapid volumetric imaging, suitable for surgical workflows. We present a surgical microscope integrated MHz-OCT imaging system, which is used for the collection of in-vivo images of human brains, with the purpose of being used in machine learning systems that shall be trained to identify and classify tumorous tissue.
