Aspects of the disclosure provide for automated self-inspection by an OCT imaging engine or device, to identify and resolve failures or inefficiencies in the hardware and/or software of the system or device during imaging. An OCT imaging engine can include a catheter connection check system for checking the quality of a physical connection point between a catheter and other components of an OCT imaging device or system. In some examples, the OCT imaging engine includes a self-inspection engine implemented to perform routine self-inspection by using a reference reflector internal to the OCT imaging engine to generate system performance data. The OCT imaging engine can use the system performance data to periodically search for and resolve failures or inefficiencies in the system. The OCT imaging engine can perform a self-calibration process to perform k-linearization and/or correct for chromatic dispersion using mirror measurements collected from an internal reference reflector.

Optical coherence tomography with self-inspecting imaging device

Aspects of the disclosure relate to systems, methods, and algorithms to perform wavenumber linearization and dispersion correction in optical systems without the need for hardware modifications, empirical adjustments, precise mirror alignment, and which can be conducted at low computational costs and in real-time. A one-time calibration process can generate spectra or calibration criteria, including wavenumber-linearization criteria, dispersion correction, and spectral flattening spectra, which can be used to correct an optical coherence tomogram in real time.
