摘要： A Fourier-domain optical coherence tomography imaging system (10) comprising an Fourier-domain optical coherence tomography scanner (20) arranged to generate complex optical coherence tomography data (25) by performing a scan of an imaging target (30) to acquire samples whose complex values are indicative of an optical property of the imaging target at respective scan locations in the imaging target. The imaging system (10) further comprises a controller (40) arranged to calculate a two-dimensional cross-correlation using phase information of the acquired samples, and control the scanner (20), based on the calculated cross-correlation, to compensate for relative movement between the imaging target (30) and the scanner (20) during the scan.
