Axons and cells
Images collected using an SRS microscope show that normal brain contains sparse cells with bundles of nerve fibers, called axons (left), but brain tumor tissue is full of cells in a disordered pattern (right). Though evident under the microscope, during surgery they are very difficult to differentiate, making it hard for a surgeon to know where the tumor stops. Raman tools could potentially provide real-time analysis with the same kind of accuracy as the path-lab micropscope. Credit: PRNewsFoto/University of Michigan Health.
