Oblique reslicing
Standard axial/coronal/sagittal slices create partial-volume artifacts when electrodes run obliquely. NeuXelec computes a custom plane perpendicular to each electrode's axis, giving a clean cross-sectional view of every contact.
- Planes are computed on-the-fly from electrode trajectory and contact positions
- Two electrodes can be displayed simultaneously side by side
- Rotate around the shaft axis with Ctrl+drag or rotation slider
- Zoom and pan within each oblique view
- A mini 3D preview shows the plane geometry in context
Multi-modal blending
Toggle CT, T1/T2 MRI, PET, and SISCOM overlays independently. Each modality has its own opacity slider (0–100%) for precise blending. PET supports percentile thresholding and gamma correction.
SISCOM overlay
The SISCOM z-score map computed in step 01 can be overlaid directly on the oblique slices. Adjust the z-score threshold and opacity to focus on regions of peak ictal activity.
Parcellation overlay
Load any FreeSurfer parcellation (aparc+aseg or custom) and toggle it on/off as a coloured overlay. Regions are labelled from the FreeSurfer colour lookup table.
Contact → region table
A live table maps every visible contact to its anatomical label from the loaded parcellation. The table updates automatically when you switch electrodes or adjust the overlay.
