Abstract
An exemplary aspect is a method of processing data acquired by applying an optical coherence tomography (OCT) scan to a sample. The method includes preparing a three dimensional data set acquired from a sample, creating a two dimensional map based on representative intensity values of a plurality of pieces of A-scan data included in the three dimensional data set, placing the three dimensional data set based on the two dimensional map, and executing a process based on at least a partial data set of the three dimensional data set on which placement based on the two dimensional map has been performed.

A method of processing data acquired by applying an optical coherence tomography (OCT) scan to a sample in a system including an OCT scanner and an OCT data processor, the method comprising:
- preparing, using the OCT data processor, a three dimensional data set acquired from a sample by the OCT scanner, the three dimensional data set being data before being subjected to an imaging process;
- creating, using the OCT data processor, a two dimensional map based on representative intensity values of a plurality of pieces of A-scan data included in the three dimensional data set;
- placing, using the OCT data processor, the three dimensional data set based on the two dimensional map;
- and
- executing a process using the OCT data processor based on at least a partial data set of the three dimensional data set on which placement based on the two dimensional map has been performed.
