[The development of a system for 3D reconstruction from DICOM data and collaborative visualization].
Complex surgeries often need multi-disciplinary surgeons to work collaboratively and set synthesized operation plans. Aided by collaboration enabled three dimensional visualization software over network, operation plans can be made more intuitively and accurately. Because different disciplinary surgeons often work at different locations, a distributed collaboration virtue environment over network should be provided. By our knowledge, such a system does not exist yet. Toward this, we implement a platform upon Client/Server architecture over network. The 3D model is reconstructed from CT image data of DICOM format and the resulting mesh is then simplified, using the Visualization Toolkit (VTK). The simplified polygon mesh data is further seamlessly integrated into our 3D graphics system developed with the HOOPS/3DAF for displaying, where the model is converted to the lossless compression stream file format-HSF, which is suited for network transmission. Using this format, a collaboration enabled interactive visualization system is implemented upon Client/Server architecture, developed with HOOPS/NET toolkit. The reconstructed 3D model is clear, and the interactive collaboration with 3D visualization is fairly real-time. We then implemented a platform for developing collaborative surgery simulation software, into which the surgery operation simulation and prosthesis design function can be easily added.
