Liver surgery planning in 3D virtual space based on reconstruction from computer tomographySojar, Valentin, medicina ...Introduction Liver surgery is still one of the most demanding fields in surgery, and planning a liver resection always presents a challenge for a surgeon. Many authors have already described ... three-dimensional (3D) reconstructions of conventional computer tornography (CT) and nuclear magneticresonance (NMR) scans, which enable precise surgery planning. But while the reconstruction can be seen, the user cannot simulate surgery. The ultimate goal has been to produce 3D reconstructions of the conventional CT orNMR slices and thus virtual environment that allows planning and simulation of the surgical procedure. Methods The project of developing a computer program for planning and simulating liver surgery had three steps: The first step was creating a 3D virtual liver and virtual environment. The second step was developing the method to reconstruct the liver from conventional CT scans.The final step was transferring the data obtained to the previously created virtual environment for manipulation. Results The result of this process is a liver surgery educational tool, which produces a virtual environment using PC based software. It provides the opportunity to manipulatea 3D liver and it is taol for studying the internal liver structuresfor all four vessels systems. The virtual environment portrays a detailed liver segmentation. The program's most important function is allowingthe opportunity to perform virtual intraoperative ultra sound on a virtual liver. The virtual liver can be dissected; the vessels can be clipped,ligated and cut. The program for 3D reconstruction from conventional CT scans has been developed so that the obtained data may be used for simulated surgery in the virtual environment. The virtual liver of the real patient has the capacity to be manipulated, cut, dissected; moreover, the intraoperative ultra sound can be performed as in the real surgery.
