1. An imaging system for a patient comprising:
an imaging probe, comprising:
an elongate shaft comprising a proximal end, a distal portion, and a lumen extending between the proximal end and the distal portion;
a rotatable optical core comprising a proximal end and a distal end, wherein at least a portion of the rotatable optical core is positioned within the lumen of the elongate shaft; and
an optical assembly positioned proximate the distal end of the rotatable optical core, the optical assembly configured to direct light to tissue and collect reflected light from the tissue; and
a console constructed and arranged to operably attach to the imaging probe, the console comprising an imaging assembly constructed and arranged to optically couple to the imaging probe, wherein the imaging assembly is configured to emit light into the imaging probe and receive the reflected light collected by the optical assembly,
wherein the reflected light comprises a back-reflection from an interface between the rotatable optical core and the optical assembly,
wherein the optical assembly is configured to produce an identifiable back reflection,
wherein the imaging assembly is configured to detect the identifiable back reflection without requiring the rotatable optical core to rotate,
wherein a change in the identifiable back reflection correlates to an undesired state of the rotatable optical core,
wherein the undesired state comprises a break in the rotatable optical core,
wherein the console is configured to determine a distance between the identifiable back reflection and a center of a calibration image formed by the directed light,
wherein the console is calibrated based on the determined distance.
