Title:
APPARATUS AND METHOD FOR ANGIOGRAPHY USING OPTICAL TOMOGRAPHY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/112162
Kind Code:
A1
Abstract:
Disclosed are an apparatus and a method for angiography using an optical tomography system. According to a specific example of the present invention, errors in extracting angiographs may be minimized by selectively emphasizing one of angiograph information (I-OAMG(x, y)) of an OAMG executing section and angiograph information (Icm(x, y)) of a cmOCT executing section in an erroneous detection area of the angiograph information and processing a final angiograph, on the basis of the intensity value of the angiograph information (I-OAMG(x, y)) of the OAMG executing section, the intensity value of the angiograph information (Icm(x, y)) of the cmOCT executing section, and a predetermined threshold value (Tm).
