Modern medical imaging techniques enable to acquire patient-related data with unprecedented accuracy. Both anatomical and functional data are acquired that provide, for example, information about brain function. The high temporal resolution of modern CT scanners allows to acquire even dynamic data. While the data obtained are often used in diagnosis, also minimally heavily. In such procedures, the surgeons often have only limited possibilities to get an overview of the surgical site and to orient themselves — which strengthens the role of visualization techniques.
In my talk I will demonstrate how visualization can help to improve such interventions by using pre-, intra- and post-operatively acquired image data. I will exemplify this by discussing three intervention types: deep brain stimulation, patella correction and liver surgery. For these examples, I will explain how visualization techniques for planning, execution and follow-up of minimally invasive procedures have been developed in close cooperation with medical researchers.
