Imaging system

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 positioned within the lumen of the elongate shaft and comprising a proximal end and a distal end;
• and
• an optical assembly positioned in the elongate shaft distal portion and proximate the rotatable optical core distal end, the optical assembly configured to direct light to tissue and collect reflected light from the tissue;
• wherein the imaging probe is constructed and arranged to collect image data from a patient site;
• an interface module comprising a retraction motive element constructed and arranged to provide a pullback force to a linkage assembly;
• a rotation assembly constructed and arranged to optically and mechanically connect to the imaging probe, and to rotate the optical assembly;
• and
• a retraction assembly constructed and arranged to mechanically connect to the imaging probe, and to retract the optical assembly and the elongate shaft in unison, wherein the retraction assembly comprises:
• a pullback module constructed and arranged to apply a pullback force from the retraction motive element and the linkage assembly to the imaging probe,
• wherein the interface module and the pullback module comprise separate housings in communication with each other by the linkage assembly.
