Objective Based on patients’ diffusion tensor imaging(DTI)，in the processing of planning stereotactic electrode insertion path，the information about neural fiber tracts surrounding the electrode contacts were presented to assist doctors to make plans for electrode insertion based on comprehensively grasping the knowledge about anatomic structure and neural connections in patients’ brain.Methods Based on the framework of 3D Slicer and idea of module design，we developed a scripted module in calculating and displaying fiber tracts around electrodes.The module could calculate contacts’ coordinates according to the manual planning of stereotactic electrode paths and present the distribution of fiber tracts around electrodes’ contacts in the planning scheme.Results After manually selected the electrode insertion paths in T1-weighted images，the distributions and connections of the neural fibers corresponding to the multiple electrode paths in the planning were revealed.According to paths’ projections in 2D slices and displaying in the pattern of the oblique plane，the relative positions of electrodes and their corresponding neural fibers were shown through the module.Conclusions On the basis of structure images，the module in this article could further provide information about the fibers’ positions and distributions around the contacts of electrodes in the manually planning，and assist doctors to plan and adjust the insertion paths of electrodes.
