Everything a clinician needs
to work with implanted brains.

Project file

One .json per patient: image paths, electrodes, markers and camera positions in a single portable file.

Save & history

Clicking the logo (top-left) prompts to save and returns to the project selection menu. Clicking the (top-right) prompts to save and closes the application. Recent projects are listed at startup, sorted by last modified.

Two opening modes

Edit mode: full access. Visualization only: navigate and export, no modifications.

01

Import &
Coregistration

Load any combination of MRI 1, CT, MRI 2, PET and SPECT. NeuXelec aligns every modality to the MRI 1 reference automatically. No manual landmark picking, no command line.

  • NIfTI, DICOM & MGZ supported
  • ANTs-powered rigid registration
  • Automatic brain mask generation
  • One-click SISCOM computation

Electrode
Reconstruction

Click two contacts on the post-implant CT. NeuXelec reconstructs the full electrode trajectory and assigns precise coordinates to every contact. Minutes, not hours.

  • Simultaneous axial, coronal & sagittal views
  • Two-point automatic trajectory estimation
  • Per-electrode color & hemisphere labeling
  • Export to BIDS, TXT, CSV, TSV, JSON, Cartool ELS & iELVIS

03

Oblique &
Parcellation

Reslice any volume along the electrode shaft for a true contact-aligned view. Overlay CT, MRI, PET and SISCOM simultaneously. A live table maps each contact to its anatomical region.

  • On-the-fly oblique plane computation
  • Multi-modal opacity blending
  • FreeSurfer & custom atlas support
  • Automatic contact to brain region table

3D View
& Export

Visualize all implanted electrodes on the patient's cortical surface. Navigate coronal, axial and sagittal slices simultaneously, then normalize to MNI space for group-level analysis.

  • Hardware-accelerated 3D rendering (PyVista / VTK)
  • Coronal, axial & sagittal slice navigation
  • MNI152 normalization & coordinate export
  • Publication-ready screenshots & GIF export
