Internal layer illumination method and apparatus for medical imaging by multiple beam interference

摘要

A novel medical imaging method has been created with theoretical demonstration for its feasibility. The method uses multi-beam interference to create destructive interference in the propagation path to reduce composite light intensity and so reduce light absorption and scattering, and to create constructive interference at a designed position to produce composite light intensity maximum which forms an internal light layer to illuminate the target tissue. This method can enhance signal strength more than 600 dB. The imaging depth can be over 5 cm in human body. The imaging resolutions are less than 1μm along object plane and near 1μm along direction of depth of field.
