The present invention relates to an apparatus for observing a surveillance lymph node in the body, and more particularly, to an apparatus for observing a surveillance lymph node by detecting near-infrared fluorescence by a fluorescent substance such as ICG in a surveillance lymph node and a near- ≪ / RTI > In particular, in the present invention, in order to realize a composite image in which near-infrared fluorescence emitted by excitation light and fluorescence substance such as indocyanine green is reproduced together with a visible light image, a color contrast using a near-infrared fluorescence image signal and a visible light reflection image signal The present invention provides a near-infrared fluorescence detection apparatus and method for a surveillance lymph node capable of detecting a surveillance lymph node with high accuracy through a method and / or a time modulation method. |
