System and method for geometric correction of OCT data representing a scan obtained by means of optical coherence tomography imaging of a sample. First scan morphological data relating to a morphology of the sample in the scan are obtained. Then reference morphological data relating to a reference morphology of the sample are obtained. For each of one or more scans of OCT data scan morphological data are compared with the reference morphological data to determine a relative geometric transformation of the morphology of the scan with respect to the reference morphology. Corrected scan is generated by performing on the OCT data representing the scan a transform that relates to the determined relative geometric transformation.

Method and apparatus for geometric correction of OCT data representing a scan obtained by means of optical coherence tomography imaging of a sample

A method and apparatus for determining the position of a feature of an object under test in a tomography image are disclosed. The method includes: determining characterizing points, in an additional image, of a feature of the object of interest; determining position data relating to the feature in the additional image based on the detected characterizing points; and identifying a feature of the object of interest in the tomography image. The determined position data in the additional image is used to guide the identification. A computer readable medium which may be non-transitory and upon execution by a processor configures a computer to perform the method is also disclosed.
