An endoscopic setup for optical coherence tomographic investigation of the urinary bladder is presented. The specific features of intravital investigation are considered. The resolving power of the method (15 μm) allows one to obtain a two-dimension

Purpose: Several investigators have demonstrated an approximately 20% higher tumor detection rate by 5-aminolevulinic acid (ALA) fluorescence endoscopy compared to standard white light cystoscopy, and suggested a reduction in tumor recurrences when f

Conventional imaging modalities like CT or ultrasonography have a spatial resolution of 70-1000 rim. OCT is a new method by which light of a certain wavelength is introduced into a fiberglass optic to measure tissue structures of up to 2.5 mm depth w

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 desc
