Comprehensive Surgical Landscape Guidance System for Immersive Assistance in Minimally-invasive and Microscopic Interventions

Duration: September 2018 – March 2022

Sponsored by the Federal Ministry of Education and Research


Minimally invasive surgery with endoscopes has become the medical standard. It promises a fast and complication-free healing. However, the restricted field of vision (keyhole surgery), instrument navigation and the orientation within and outside the situs pose high challenges for technology, the surgeon and the entire clinical OR staff.

Goals and Approaches

The COMPASS system is intended to recognize the surgeon's navigation process by means of an understandable, immersive visualization and interaction, to navigate him foresighted and to accompany him through the surgical procedure. An "anatomical map" of the patient is created from images of a 3D endoscope. On this map, distinctive anatomical regions, risk structures, directions and information on the surgical steps are entered and adapted according to the endoscope position. The surgeon navigates through the patient's body and can interact with the COMPASS OR navigation system and retrieve relevant surgical information. The procedures are being developed in cooperation with clinical partners in Leipzig and Munich.

Innovation and Outlook

The COMPASS system aims to eliminate the disadvantages of common surgical navigation methods such as electromagnetic tracking (interference) or optical IR tracking (line-of-sight problem) and replace them with purely image-based 3D algorithms. These methods will be transferred into an integrated endoscopic 3D imaging and navigation system.
