METHOD AND DEVICE FOR PERFORMING OPTICAL MEASUREMENT BY USING OPTICAL FIBER IMAGING GUIDE WIRE, CATHETER OR ENDOSCOPE

摘要

PROBLEM TO BE SOLVED: To overcome the problems related to restrictions of a conventional imaging method and conventional technique, to provide a high-resolution image, and to enable a medical attender to observe treatment or to assist actively control of a treatment process during the treatment by being used during the medical treatment. SOLUTION: This optical imaging system is equipped with an endoscope unit, and an interferometer for executing multi-dimensional scanning of a structure by utilizing an optical coherence tomography(OCT). In the system, high- resolution imaging of the structure is performed by using the OCT. In the OCT, optical characteristics of the structure are measured by interference measurement by using a light source having a short coherence length or an adjustable frequency.
