Two-point reconstruction
The core workflow is simple: click the deepest contact and the most superficial contact of the same electrode on any slice view. NeuXelec uses the electrode's known inter-contact spacing to automatically estimate every contact in between along the trajectory.
- Works on axial, coronal, or sagittal views: any view, any time
- Optional local-max snapping to peak CT intensity for sub-voxel accuracy
- Estimates are shown immediately in all three views and in 3D
- Any contact can be manually adjusted after estimation
Synchronized orthogonal views
Axial, coronal, and sagittal CT slices are shown simultaneously with a shared crosshair. Clicking in any view moves the crosshair in all three. Navigate to any contact in one click.
Per-electrode properties
Each electrode gets a name, hemisphere assignment (L/R), contact count, inter-contact distance, and a custom colour. Contacts are numbered automatically from deepest to shallowest.
All SEEG configurations
Electrode reference files are pre-loaded for all Dixi Medical SEEG electrodes, covering the full range of contact counts and spacings. It is also possible to define a custom electrode by specifying contact count, inter-contact distance, and skipped contacts. Parameters auto-fill from the reference once selected.
Coordinate export
Export all contact positions as CSV or BIDS-compatible TSV. Coordinates are given in both voxel indices and physical LPS millimetres. MNI coordinates are added after normalization.
Display & navigation
- Mouse wheel to zoom; shift+wheel to scroll slices
- Drag to move crosshair; shift+drag to pan zoomed view
- Double-click to reset view
- Radiologic or neurologic orientation (flip L/R)
- Ctrl+D sends current crosshair position to the 3D view as a marker
- All reconstructed contacts are shown as coloured dots on every slice
