Final Report Abstract

The brightest minds of our generation are working on digitizing and integrating all areas of life to find smart solutions for the challenges of the 21st century. While economy and society have since experienced groundbreaking innovations, minimal progress has been made in the field of surgery. Due to the technological leeway, the success of surgical treatment remains highly dependent on the knowledge and experience levels of surgical teams. The vision of the Transregional Collaborative Research Center 125 “Cognition-Guided Surgery” was therefore to develop a technical-cognitive system that behaves like a humanoid assistant, supports the surgeon during the course of the operation and learns from experience. For this purpose all information along the surgical treatment path should be gathered (perception) to derive the current state of treatment plans, tissue characteristics or the condition of patients (interpretation) and to generate an assistant function for the surgeon (action). After completion, each action was to be evaluated and stored in the knowledge base so that it could be reused for future operations (learning). Over the course of the funding period, basic methods for the concept of “Cognition-Guided Surgery” were explored. Innovative concepts for quantification of preoperative perfusion parameters (radiological imaging) as well as intraoperative geometric patient parameters (mitral valve size, small bowel length) for objective diagnosis and therapy of surgical diseases were investigated. For the first time it was possible to collect and incorporate different forms of surgical information. This was achieved by means of a common knowledge base, by formalizing surgical factual knowledge and by developing new methods for data annotation (crowd sourcing, sparse annotations). With regard to interpretation, it was possible for the first time to fuse stand-alone solutions into a knowledge-based main framework for surgical applications. This was achieved by means of semantic modeling of patients and processes (patient factor model, OntoSPM) and by integrating image-processing algorithms and simulation processes. Based on these methods, clinical applications could be developed that performed cognitive actions. Applications that were internationally awarded were an assistance system for treatment planning in liver surgery that incorporates heterogenous information, knowledge-based selection of different mitral valve prosthesis in cardiothoracic surgery and a learning camera robot in laparoscopic colorectal surgery. The SFB/Transregio 125 investigated cognition-guided surgery in terms of universal, technical, cognitive assistance systems. Through development of prototypes for cognitive systems, surgical decision making could be facilitated in the future by receiving individual, precise, context aware treatment suggestions that result in safer and more effective treatment for patients.
