Claim:
1. A reconfigurable optical coherence tomography (OCT) system configured to reconfigure between at least a first imaging mode optimized for coronary imaging and a second imaging mode optimized for peripheral imaging, the system comprising: a reconfigurable swept-source laser configured to be adjusted between a first setting corresponding to the first imaging mode and a second setting corresponding to the second imaging mode, wherein the reconfigurable swept-source laser comprises: wherein, in the first setting, the swept-source laser has a first sweep rate with a first coherence length and the first imaging mode is for imaging a coronary vessel; and wherein, in the second setting, the swept-source laser has a second sweep rate with a second coherence length, the second sweep rate being less than the first sweep rate and the second coherence length being greater than the first coherence length, and the second imaging mode is for imaging a peripheral vessel; wherein sampling characteristics of OCT signal digitization are changed between the first and second imaging modes by changing an external K-space sample clock waveform by switching a different wavemeter interferometer into a K-clock generator for each of the imaging modes.
