Imaging Target Movement Compensation in a Fourier-domain Optical Coherence Tomography Imaging System

A computer-implemented method of controlling a Fourier-domain optical coherence tomography, FD-OCT, scanner, which is generating complex OCT data by performing a scan of an imaging target to acquire samples whose complex values are indicative of an optical property of the imaging target at respective scan locations in the imaging target, to compensate for a relative movement between the imaging target and the FD-OCT scanner during the scan, the method comprising:

• performing a cross-correlation calculation that uses phase information of the acquired samples;
• and
• controlling the FD-OCT scanner, based on the cross-correlation calculation, to compensate for the relative movement between the imaging target and the FD-OCT scanner during the scan.

A computer program comprising computer-readable instructions, which, when executed by a processor that is controlling a Fourier-domain optical coherence tomography, FD-OCT, scanner to generate complex OCT data by performing a scan of an imaging target to acquire samples whose complex values are indicative of an optical property of the imaging target at respective scan locations in the imaging target, cause the processor to control the FD-OCT scanner to compensate for a relative movement between the imaging target and the FD-OCT scanner during the scan, by performing a method comprising:

• performing a cross-correlation calculation that uses phase information of the acquired samples;
• and
• controlling the FD-OCT scanner, based on the cross-correlation calculation, to compensate for the relative movement between the imaging target and the FD-OCT scanner during the scan.
