  • Patent number: 10470665
    Abstract: An imaging apparatus is disclosed for diagnosis, which can automatically discriminate an optical refractive index of flushing liquid which is utilized during pull-back scanning, and reconstruct a blood vessel cross-sectional image having an appropriate scale. An intensity of reflected light in a medium having a known refractive index is obtained in advance. An intensity of the reflected light on a border surface between a catheter sheath unit and the flushing liquid is detected based on interference light data, which is obtained during the pull-back scanning. The refractive index of the flushing liquid is calculated based on the intensity of the reflected light, an intensity of incident light obtained from the stored reflected light, and a known refractive index of the catheter sheath unit.
