High spatial resolution terahertz imaging of carcinoma tissues at 0.6 THz frequencies

The terahertz (THz) imaging enhanced with compact diffractive lenses and sensitive room temperature THz detectors was demonstrated to be suitable for carcinoma zones screening in bio-tissues. Optical transmission of the dehydrated histological sections with a colon cancer was measured with close to...

Summary:The terahertz (THz) imaging enhanced with compact diffractive lenses and sensitive room temperature THz detectors was demonstrated to be suitable for carcinoma zones screening in bio-tissues. Optical transmission of the dehydrated histological sections with a colon cancer was measured with close to wavelength-limited spatial resolution at 0.6 THz frequencies. High number of the explicit areas where THz absorption values varied up to two times was found only in the carcinoma tissues indicating the new potentials of the sub-wavelength THz imaging in the field of medical diagnostic.
