The Diagnosis of Human Liver Cancer by using THz Fiber-Scanning Near-Field Imaging

Based on a room-temperature-operated THz fiber-scanning near-field imaging system, we demonstrate the capability of THz imaging for diagnosing human liver cancer. By THz near-field mapping of the absorption constants of liver tissues, the acquired images can clearly distinguish cancer from normal tissues fast, automatically, and correctly without pathological H&E staining examination. Accordingly, the studied THz imaging system has valuable potential applications in clinical cancer diagnosis. With the help of THz imaging, we can expect to economize the use of hospital and human resources.
