Description
Summary:Background So far, conventional navigation systems do not provide the opportunity for any modification of acquired image datasets. In particular, the surgical progress in the operating field cannot be visualized unless new imaging scans are performed. Methods In a feasibility study, new software creating intra‐operative image updates by virtual means was tested in conjunction with conventional navigation. With this new software, surgically removed tissue volumes can be traced and viewed directly within the diagnostic image data. Results and Conclusions The new software represents an interesting and helpful amendment to conventional computer‐assisted surgery in selected cases. During surgical procedures around bony structures, the surgeon gets an accurate virtual image update of the surgical progress in the operating field and the amount of tissue removed. However, in cases where mobile structures are present or soft tissue shifts are expected, this feature seems to be suitable only to a limited extent. Copyright © 2008 John Wiley & Sons, Ltd.
