Functional Neurosurgery Planning Assisted by the Probabilistic Functional Atlas of the VIM Nucleus Co-registered with the Schaltenbrand-Wahren Atlas

摘要

The probabilistic functional atlas (PFA) aggregates knowledge gathered by operating on numerous stereotactic cases and presents it in form of images representing the distribution of best stereotactic contacts [1]. The probability at a given point is then proportional to the fraction of all best contacts containing this point. The algorithm for generation of PFA is detailed in [2] and [3] addresses the calculation of PFA for the subthalamic nucleus (STN). Combination of PFA with an anatomical atlas, such as the Schaltenbrand-Wahren atlas (SWA) [9], may provide a more efficient targeting and trajectory planning. Therefore, an electronic version of SWA [4] was co-registered spatially with the PFA-STN [6]. Subsequently, an application was developed for targeting and trajectory planning by means of the combined SWA-PFA-STN [6].
