Abstract: The invention relates to a control system (130) for controlling optical coherence tomography imaging means for imaging a subject (190), the control system being configured to perform the following steps: receiving scan data (122) from the subject (190) being acquired by means of optical coherence tomography, performing data processing on the scan data (122), and obtaining image data (142) for an image (144) of the subject, and the processing system (130) further being configured to adapting, based on a change of a value, the value characterizing an axial position (z) of the subject (190) with respect to the OCT imaging means, between two sets of image data, at least one parameter of the OCT imaging means, to a processing system, to an OCT imaging system (100) and a corresponding method.

Abstract: A system for identifying presence of a conjugate in an image comprising one or more processors and one or more storage devices is provided. The system is configured to acquire spectral data associated with a sample to be imaged. Dispersion coefficients are optimized for acquired spectral data. A corrective phase function is calculated using the optimized dispersion coefficients. A negative corrective phase function is applied to a signal to provide a resulting image. It is determined if the resulting image has degraded signal strength or an enhanced signal strength relative to an original image. A reference arm shift is calculated if it is determined that the resulting image has enhanced signal strength. A position of a reference arm of the system is adjusted based on the calculated reference arm shift to move a conjugate image out of view.
