Paper Abstract

Combining endoscopy with optical coherence tomography (OCT) can improve the diagnosis in minimal invasive procedures. Up to now OCT probes were constructed using rotating or moving single-mode fibers or micro scanners at the tip of the probe. We describe an endoscopic OCT system which uses a specially designed rigid endoscope with an extracorporal scanner to create OCT images with 15 μm resolution. The OCT endoscope was constructed using a 270 mm gradient index lens with a diameter of 3 mm. Dispersion of the endoscope was compensated in the OCT interferometer by an all fiber approach. The system is now being tested for detecting malignancies in the urinary bladder.
