<P>PROBLEM TO BE SOLVED: To provide an optical tomographic imaging apparatus reducing image blurring caused by movement of a subject when imaging a tomographic image with an OCT (optical coherence tomography) system of a high transverse resolution. <P>SOLUTION: The optical tomographic imaging apparatus to image a tomographic image of a subject with the OCT system comprises a means for synchronizing a first irradiating beam of a larger spot diameter and a second irradiating beam of a smaller spot diameter on the subject and to scan them, an image information acquisition means for scanning the first and second irradiating beams by the scanning means to acquire first image information by the first irradiating beam and second image information by the second irradiating beam, and an image information position correction means for identifying the position of the first image information based on reference image information acquired in advance to parallelize the position of the second image information to the identified position of the first image information by the correlation of the positions of the first image information and the second image information so that the position of the second image information could be corrected. <P>COPYRIGHT: (C)2010,JPO&INPIT |
