Patent number: 11627880Abstract: The present invention relates to a real-time parathyroid imaging apparatus including: a light source including an excitation filter capable of exciting parathyroid glands; and a camera including an image sensor and an emission filter of which a transmissivity ratio between a visible light region and a near-infrared emission wavelength region is N:1 (here, N<1). Through the present invention, a system may be implemented whereby a surgeon may acquire, in real-time during an operation, an autofluorescence image of the parathyroid glands by using a near-infrared light source, and an auto focus function may be used, and visible light and near-infrared autofluorescence images may be simultaneously fused and acquired without having to turn off the lights in an operating room.Type: GrantFiled: November 5, 2018Date of Patent: April 18, 2023Assignees: PUKYONG NATIONAL UNIVERSITY INDUSTRYUNIVERSITY COOPERATION FOUNDATION, UNIST (ULSAN NATIONAL INSTITUTE OF SCIENCE AND TECHNOLOGY)Inventors: Yeh-Chan Ahn, Sung Chul Bae

Patent number: 11559248Abstract: The present invention relates to a parathyroid sensing system, and includes: a modulator for generating a modulation signal having a predetermined frequency; a lock-in amplifier and a light source which receive information on the modulation signal; an excitation filter for transmitting, among light emitted from the light source, only excitation light that excites parathyroid glands; an emission filter connected to a probe and selectively transmitting only fluorescence emitted from the parathyroid glands; a near-infrared sensor for sensing the autofluorescence that has passed through the emission filter, and converting the sensed autofluorescence into an electric signal; and a speaker for generating an alarm through the electric signal. Through the present invention, the locations of the parathyroid glands may be precisely identified even when lights are turned on in an operating room, and convenience may be provided by alerting a surgeon by means of an alarm when the parathyroid glands are detected.Type: GrantFiled: November 5, 2018Date of Patent: January 24, 2023Assignees: PUKYONG NATIONAL UNIVERSITY INDUSTRYUNIVERSITY COOPERATION FOUNDATION, UNIST (ULSAN NATIONAL INSTITUTE OF SCIENCE AND TECHNOLOGY)Inventors: Yeh-Chan Ahn, Sung Chul Bae

Publication number: 20190320999Abstract: The present invention relates to: a portable probe for photoacoustic tomography, capable of performing line-by-line scanning or area-by-area scanning by using a small number of light inputs; and a real-time photoacoustic tomography device. The probe for photoacoustic tomography includes: a lens receiving light inputs from an optical fiber so as to make the same proceed as small diameter parallel light; a Powell lens receiving the small diameter parallel light and generating a line beam of a predetermined thickness, and allowing energy dispersed on a line to be uniform on the entire line; a lens making the line beam pass therethrough such that the line beam has a predetermined width and a reduced thickness so as to be line-focused at a target area; an acoustic reflection glass for separating, from a light path, an acoustic wave outputted from the target area; and an acoustic measurement unit for measuring acoustic strength.Type: ApplicationFiled: October 23, 2017Publication date: October 24, 2019Applicant: PUKYONG NATIONAL UNIVERSITY INDUSTRY-UNIVERSITY COOPERATION FOUNDATIONInventors: Sung Chul BAE, Chul Ho OAK, Eun Kee PARK, Jung-Eun PARK, Yeh Chan AHN
