    Osteoarthritis (OA) is a major musculoskeletal disorder which causes are not always fully understood. Femoroacetabular impingements such as cam/ pincer cannot always explain observed OA in hips with normal morphology. This paper investigates the hypothesis of extreme repetitive movements as a source of cartilage degeneration. We present a clinical study conducted with professional ballet dancers and a methodology to perform functional simulations of the hip joint in extreme postures. Throughout the process, various computer graphics techniques are used, like motion capture, 3D body scanning and physically-based models. In addition to accelerate and strengthen some tasks, these techniques strongly participate in the clinical understanding of OA related to motion. Preliminary results have indeed shown a significant correlation between the location of impingements and radiologically observed damage zones in the labrum cartilage.

    We present an integrated system for training visceral needle puncture procedures. Our aim is to provide a cost effective and validated training tool that uses actual patient data to enable interventional radiology trainees to learn how to carry out image-guided needle puncture. The input data required is a computed tomography scan of the patient that is used to create the patient specific models. Force measurements have been made on real tissue and the resulting data is incorporated into the simulator. Respiration and soft tissue deformations are also carried out to further improve the fidelity of the simulator.

    GREiF - Graphical Documentation of Retinal Findings Using a Standardized Digital Symbol Library
    (The Eurographics Association, 2009) Jürgens, Clemens; Großjohann, Rico; Tost, Frank; K. Bühler and D. Bartz
    Aim: To develop a software package that improves standardized clinical documentation of retinal findings. In clinical routine retinal findings are usually documented with sketchy free-hand drawings and supplementary handwritten remarks. Documentation features of common ophthalmologic software products include only simple sketching functions, which are limited to change location, size or colour of graphical primitives (e. g. ovals, rectangles, lines, textboxes . . .). As a result a feasible creation of standardized graphical documentations in retinal imaging is almost impossible. Methods: We developed a java-based software tool that features quick and intuitive generation of fundus schemes, which can be printed as findings sheet or digitally archived. Particularly for clinical ophthalmologists we created a set of standardized symbols, which can be digitally rendered for graphical documentation. All symbols were integrated into a graphics library and separated in specific categories: "Preoperative", "Postoperative", "Angiomas and tumours", "Retinopathy of the premature". The required symbol can be chosen from the library and is simply modelled on the retina scheme by placing anchor points with mouse clicks. Results: Practicability of existing features for graphical documentation of retinal findings is not sufficient, because free-hand drawings are too time-consuming and besides share the risk of false interpretation due to individual handwritings. In contrast to free-hand sketching our software tool not only applies a faster way of graphical creation but additionally improves medical documentation using a standardized symbol library, which also is specifically categorized. Conclusions: Graphical symbols for retinal documentation have found universal acceptance in ophthalmologists for a long time but still the practical use is not efficient in clinical routine. This report shows how the adequate use of software technology can contribute to documentation quality and clinical practice.

    Advanced GPU Volume Rendering for Virtual Endoscopy

    For difficult cases in endoscopic sinus surgery, a careful planning of the intervention is necessary. Virtual endoscopy enables the visualization of the operating field and additional information, such as risk structures and target structures to be removed. The Sinus Endoscopy system provides the functional range of a virtual endoscopic system with special focus on a realistic representation. Furthermore, by using direct volume rendering, we avoid time-consuming segmentation steps for the use of individual patient datasets. However, the image quality of the endoscopic view can be adjusted in a way that a standard computer with a modern standard graphics card achieves interactive frame rates with low CPU utilization. Thereby, characteristics of the endoscopic view are systematically used for the optimization of the volume rendering speed. As a small standalone application it can be instantly used for surgical planning and patient education. The system was used for preoperative planning in 102 cases, provides useful information for intervention planning (e.g., anatomic variations of the Rec. Frontalis), and closely resembles the intraoperative situation.
