Patent number: 9795338Abstract: The present invention relates to a device for observing a sentinel lymph node (SLN) in a human body. More particularly, the present invention relates to a device for observing an SLN by detecting near-infrared (NIR) fluorescence caused by a fluorescent material such as indocyanine green (ICG) at the SLN and a method for detecting NIR fluorescence at an SLN. Particularly, in the implementation of a composite image obtained by reproducing a fluorescent material such as ICG and NIR fluorescence emitted by excitation light together with a visible light image, it is possible to detect an SLN with high accuracy through a color contrast method and/or a temporal modulation method using an NIR fluorescence image signal and a visible reflection light image signal.Type: GrantFiled: July 10, 2014Date of Patent: October 24, 2017Assignee: INTHESMART CO.

Publication number: 20140046409Abstract: Disclosed herein is a light source apparatus for photo-diagnosis and phototherapy. The light source apparatus includes a first light source, a second light source, a light-guide, an interference filter, and a compensation filter. The first light source is non-coherent, and the second light source is coherent. The light-guide delivers light emitted from the first light source and the second light source. The interference filter is disposed on an optical path of the first light source. The compensation filter is disposed between the first light source and the light-guide, and compensates for an output spectrum of the first light source and converts the output spectrum of the first light source into a predetermined reference output spectrum. Here, the light emitted from the second light source is reflected by the interference filter to be incident to the light-guide and the light from the first light source passes through the interference filter at the same time.Type: ApplicationFiled: March 29, 2013Publication date: February 13, 2014Applicant: KOREA ELECTROTECHNOLOGY RESEARCH INSTITUTEInventors: Uk KANG, Dae Sic LEE, Guang Hoon KIM, Min Woong JUNG, Garry V.
