Title:
OPTICAL TOMOGRAPHIC IMAGE FORMING METHOD
Document Type and Number:
WIPO Patent Application WO/2010/050296
Kind Code:
A1
Abstract:
Provided is an optical tomographic image forming method capable of acquiring a more real tomographic image.
Refractive indexes (n1 to n3) of first to third layers (S1 to S3) are inputted through an input means (ID). In a personal computer (PC), corrections are made such that the optical path length of a measurement light (L1) to pass through the first layer (S1) is multiplied by times (n0/n1) with respect to an optical tomographic image obtained from a tomographic signal. Moreover, the optical path length of the measurement light (L1) to pass through the second layer (S2) is multiplied by times (n0/n2), and the optical path length of the measurement light (L1) to pass through the third layer (S3) is multiplied by times (n0/n3). The refractive indexes (n1 to n3) of the first to third layers (S1 to S3) can also be exemplified by either the refractive index which is actually measured in tissues or the like extracted by surgical operation, or the refractive index of a substance similar in components or the like.
