Abstract: The invention relates to a control system (130) for an imaging system (100) for real-time imaging of a subject (190), using optical coherence tomography and video imaging, the control system (130) being configured to: control the imaging system (100) to determine, from a video image (152) of the subject (190), a position and/or an orientation (152) of a tissue of interest (192) in the subject (190), control the imaging system (100) to perform a scan of the subject (190) by means of optical coherence tomography, wherein a position and/or an orientation (144) of the scan is determined based on the position and/or orientation (154) of the tissue of interest (192) in the video image (152), and provide an optical coherence tomography image (142) of the subject (190), including the tissue of interest (192), based on the scan, to an imaging system (100) and 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.

Abstract: The invention relates to a control system for an optical coherence tomography imaging system to be used with a microscopy system for viewing and/or imaging a subject (190, 192), the microscopy system comprising an objective (164) and a viewing lens system (170) including a relay lens (172), wherein the viewing lens system (170) is arranged at a subject’s side of the objective (164), the control system being configured to perform the following steps: controlling the optical coherence tomography imaging system to perform at least one radial scan of a surface (176) of the relay lens (172), determining, from data of the at least one radial scan at least one curve corresponding to a shape of the surface (176) of the relay lens (172), determining (520), from the at least one curve a lateral offset (178) between a center of the relay lens (172) and an origin of the optical coherence tomography imaging system, and adjusting the origin of the optical coherence tomography imaging system taking into account to the lateral offset (178), to an arrangement with an OCT imaging system and a method for adjusting an OCT imaging system.
