Short summary
Computed tomography (CT) is an important imaging technology which enables minimally invasive procedures. Uncertainties in imaging lead to erroneous initial conditions for the navigation process during minimally invasive surgery and result in a higher risk of unintended injuries. To minimize the risk, the uncertainties of the imaging process need to be estimated and considered during the planning of a procedure. A method for estimating the uncertainty is demonstrated.
