(canceled)
A method of performing atherectomy, comprising:
- inserting an atherectomy device into a vessel;
- gathering optical coherence tomography (OCT) images using an imaging sensor on the device, wherein the OCT images provide a toroidal view of the vessel;
- identifying an external elastic lamina in the OCT images by identifying an outer-most bright line in the toroidal view;
- and
- cutting tissue in the vessel based upon the identification.
