I have included a lecture I gave at Duke in 1998.  This illustrates not just the state of the field, but how we left clinical trials to others.  This would effect the field for the next two decades.  Note also how thinking on PS-OCT was evolving and the attack on imaging in non-transparent tissue.  The Duke shows the state of OCT in 1998..  Catheter, acquisition rate, resolution, imaging coronary plaque, PCI, and polarization sensitive OCT (PS-OCT).
