A new method of imaging brain tumors helps surgeons see precisely where the tumor ends and healthy tissue begins, guiding the doctor through the surgery.
Called stimulated Raman scattering (SRS) microscopy, the technique works by hitting the brain with a non-invasive laser, and then analyzing the spectrum of light that emerges. The system is able to sense the vibrations of chemical bonds, with healthy tissue and tumors differentiated by the amount of lipids and proteins in the cells. The data is transmitted as a color code, with the healthy tissue showing as green while the protein-rich tumors are displayed as bright blue.
In tests, the system was able to create 30 new images per second—allowing the surgery team to keep track of tumor removal in real time.
