Advances in Endoscopic Optical Coherence Tomography Catheter Designs

The use of endoscopic Optical Coherence Tomography (OCT) in the clinical setting has gained momentum in recent years. This is largely due to the advances in OCT catheter designs that are tailored to specific clinical applications. In this review, we summarize many of the designs currently used in patient studies, and additionally discuss a number of novel designs that are yet to be implemented and tested in the clinical setting. With advances in endoscopic OCT catheter designs, we are now beginning to uncover the true clinical potential of this technology particularly in screening, surveillance, biopsy guidance, diagnosis, and therapy-monitoring applications.
