摘要: This work presents the development and application of a visualization navigation system for planning deep-brain neurosurgeries. system, which incorporates digitized segmented brain atlas, an electrophysiological database, collections final surgical targets previous patients, provides assistance non-rigid registration, navigation, reconstruction clinical image data. The fusion standardized anatomical functional data, once registered to individual patient images, facilitates delineation targets. Our preliminary studies compared target locations identified by non-expert using this with those located experienced neurosurgeon regular technique on 8 patients who had undergone subthalamic nucleus (STN) stimulations (DBS). average displacement between in both groups was 0.58mm ± 0.49mm, 0.70mm 0.37mm, 0.69mm 0.34mm x, y, z directions respectively, indicating capability accurate initiation our has also shown promise guidance other stereotactic neurosurgical procedures.
