Abstract: The invention relates to a control system for controlling optical coherence tomography imaging means for imaging a subject, the control system being configured to perform the following steps of an imaging process: receiving (212) a scan data set from the subject being acquired by means of optical coherence tomography, the scan data set including one or several spectra (270), performing (214) data processing on the spectrum or on each of the several spectra of the scan data set (122), including per spectrum: determining (216) a scaling factor (274) for the spectrum (270, 370, 372, 374), scaling (218) a baseline spectrum (272) with a scaling factor (274), and removing (220) the scaled baseline spectrum (276) from the spectrum (270); and providing (224) a baseline corrected image data set of the subject for an image of the subject to be displayed, to an optical coherence tomography imaging system and to a corresponding method.

Abstract: The invention relates to a processing system for use with optical coherence tomography imaging means for imaging a subject, the processing system being configured to repeatedly perform an image processing process (300), comprising the following steps: receiving (312) a scan data set from the subject (190) being acquired by means of optical coherence tomography, performing (314) data processing on the scan data set, including applying (316) dispersion correction based on a current set (370) of dispersion coefficients, and providing (318) a dispersion corrected image data set of the subject for an image of the subject to be displayed; and the processing system further being configured to repeatedly perform a dispersion coefficient adapting process (340), at least in part, in parallel to the image processing process (300), comprising the following steps: receiving (342) a scan data set from the subject being acquired by means of optical coherence tomography, adapting (344) dispersion coefficients by means of an optimization process (346) performed on the scan data set, and providing (348) a set (372) of adapted dispersion coefficients to be used to update the current set (370) of dispersion coefficients; and the processing system further being configured to update (350) the current set (370) of dispersion coefficients based on the set (372) of adapted dispersion coefficients, to an optical coherence tomography imaging system and a corresponding method.
