ESBS 2005: Skull Base Surgery: An Interdisciplinary Challenge;
7th Congress of the European Skull Base Society held in association with the 13th Congress of the German Society of Skull Base Surgery;
Aim of this study was to develop a software to enhance preoperative planning based on segmentation and to evaluate the different results of 3-dimensional visualization by surgeons. 11 CT-datasets were processed by using classic algorithms of image analysis. A smart medical 3-D-visualization was designed by using standardised object colours, transparency values and viewing directions. Automated measurement tools computed distance and volume which is helpful in operative planning for every individual patient. Silhouette generation algorithms enhance the visualization of transparently rendered objects. A variety of emphasis techniques like shadow generation for selected objects are shown to be suitable for medical visualization. The clinical use and acceptance by surgeons could be pointed out. The results are basis for individual operative planning and simulation but do not substitute original data.
