Deformities of the spine caused by an accident or by a birth defect may cause severe pain and functional impairment. Spine reconstruction by surgical treatment is used to achieve spinal balance, stability, and anatomical alignment. One important aspect for patients who undergo spinal surgery is the aesthetic aspect of the surgical outcome. It would be very helpful to be able to predict the postoperative trunk appearance of a patient, already in the preoperative planning stage.

A first step in simulating postoperative appearance is to predict the appearance of the surrounding anatomy (e.g., shape, position) after surgery which will be the goal of this project. That is, given triangular surface models of the trunk anatomy (e.g., spine, other bones, soft tissue structures) before surgery and the surgical plan (i.e., the modification of the spine) , a method has to be developed that simulates the effects on the surrounding anatomy. In the project, it is not necessary to achieve a biomechanically realistic simulation, visual appearance may be able to predict with other lower-complexity simulation techniques.

 The project will be jointly supervised by the Computer Vision Laboratory of ETH and the University Hospital Balgrist. Required fundamentals in anatomy and clinical biomechanics will be provided by a dedicated supervisor at Balgrist.

 You should have a solid background in computer graphics and/or simulation and strong programming skills. Experience in VTK and SOFA are advantageous.
