Image Guidance and Precision Oncology

Medical imaging is essential for the surgical planning process and for indications for medical intervention. Therefore, it is highly important to make full use of the various virtual imaging techniques' potential to provide a broad range of medical information.

3D Visualization and its role in medical education and the communication between patients and doctors

Imaging is the first and overall one of the most important steps for surgical planning and decision making in clinical routine, thus it is of major interest to read out the whole information provided by the particular imaging technique. For instance, post-processing techniques of CT-A or MR-A with 3D visualization have shown to provide a better diagnostic efficacy compared to 2D visualization [1-3]. In this context, we have shown that stereoscopic visualization of 3D CT-A images with perception of depth could further increase the diagnostic efficacy of these imaging technique and consecutively reduce the need of further invasive diagnostic tools [4].

Stereoscopic displays have increasingly been used in medicine in the last years with main domains in pre-operative planning and teaching [5, 6]. Stereoscopic visualization has also been shown to be beneficial in neurosurgical research and education [7]. Thus, the major focus of our research group is to analyze the advantages of stereoscopic visualization in neurosurgery including diagnostic efficacy, training and patient communication.
