Virtual reality in GI endoscopy: intuitive zoom for improving diagnostics and training

Message

Among the many areas which may benefit from virtual reality (VR), GI endoscopy could be an important one. We developed a system to magnify the endoscopic image on forward movement of the endoscopists head to zoom into areas of interest during real-time endoscopy, called intuitive zoom. We could show that VR could be conveniently incorporated into daily endoscopic work when it comes to closely examining operator-defined regions of interest. Additionally, applied light intensity-derived three-dimensional (3D)reconstruction of the intestinal mucosa was used to better assess lesions such as polyps using the Paris classification. These new techniques might improve routine endoscopic diagnosis and therapy and open a new world of endoscopic training.

In more detailStudy background

Flexible endoscopy is performed using a two-dimensional (2D) image of the working area. Although this is regarded as a standard since 1970,1 new technologies allowing for stereoscopic vision thus improving visual spacial perception emerge....
