Miniaturized Piezo Tubes In High-Resolution Scanning Fiber Endoscopy

GettyImages-981992634 Endoscope

High-definition endoscopes are increasingly being used in medicine not only for diagnosis, but also for the therapy of diseases. Due to their compact and flexible architecture of only a few millimeters in diameter, they allow less invasive procedures. Contrary to previous limitations of image quality in conventional endoscopes, the innovative design of scanning fiber endoscopes (SFE) offers new possibilities: SFE generate laser-based, full-color images with higher resolution and an enlarged field of view, e. g. in optical coherence tomography.

With their fast deflection and control, miniaturized piezo tubes generate a scanning movement of the optical fiber in the SFE. SFEs thus provide more image information, new findings in biomedical research and improved minimally invasive procedures in everyday clinical practice.
