New fiber optic probe brings endoscopic diagnosis of cancer closer to the clinic
(PHYSorg.com Physics)

In an important step toward endoscopic diagnosis of cancer, researchers have developed a handheld fiber optic probe that can be used to perform multiple nonlinear imaging techniques without the need for tissue staining. The new multimodal imaging probe uses an ultrafast laser to create nonlinear optical effects in tissue that can reveal cancer and other diseases.
