The device is shown to accurately identify tissues and surgical margins directly in patients and differentiate healthy and cancerous tissue from banked pancreas samples. At about 15 seconds per analysis, the method is more than 100 times as fast as the current gold standard diagnostic, Frozen Section Analysis. The ability to accurately identify margins between healthy and cancerous tissue in pancreatic cancer surgeries can give patients the greatest chance of survival.
