Volume Holographic Imaging System (VHIS) Endoscope

Detailed Technology Description

Background:  An endoscope is an instrument that allows a doctor or surgeon to look inside the body through existing openings or through small incisions. The endoscope is a metal tube that that has a small light source and camera at one end and an eyepiece at the other. Endoscopes may be made from a rigid tube or, more often, from a flexible tube that allows the surgeon to freely move and adjust it as it enters the area that is being observed. Advances in the technology over these past several decades have added a wide variety of optional equipment to be used with the basic endoscope. Invention:  The investigators have developed a hand-held version of the Volume Holographic Imaging System (VHIS) microscope suitable for use as an endoscope to be employed in a clinical setting by a physician. The imaging system is modular by design, with interchangeable components, and offers two illumination options. The endoscope barrel is tailored to the particular requirements of the application, and can provide high-resolution images on a cellular level. Advantages:Faster video and image acquisition than confocal microscopes or optical coherence tomography - no scanning required;Simultaneous image acquisition from multiple object planes;Can accomodate traditional and fluorescene modalities;This device can capture 3-D information about an object at camera frame rates. Market:  The endoscopy market worldwide projection for 2011 is nearly $24.8 billion, and this is anticipated to increase to $33.7 billion by 2016 at a compound annual growth rate (CAGR) of 6.4%. The largest increases in revenue are projected to occur in the areas of; laparoscopy, arthroscopy, gastroenterology (GI) endoscopy, and ear, nose and throat (ENT) endoscopy. Status:  This technology has been reduced to practice, and work on this subject is continuing under a large NIH Grant. A major area of continued refinement of the instrument deals with stray light management; this ultimately defines the fundamental limitation to image contrast. The University of Arizona is seeking potential licensing partners and parties interested in working with the inventors to realize this novel high-speed, 3D endoscope. The patent application has published on 25 April 2013 as WO/2013/059727. Keywords:  Volume Holographic Imaging System, Endoscope Lead Inventor:  Raymond Kostuk UA ID:  UA12-016
