Stereotactic tools for DBS and intraEEG exploration procedures

• Jordan Cornillault (ICM)
• Eric Bardinet (ICM)

Project Description

To improve and update the Slicer plug-ins we have developed for pyDBS and EpiLOC toolboxes.

Objective

1. PyDBS PostOperative Report Plug-in. pyDBS is use mostly to localize the electrodes implanted in some regions of the Basal Ganglia, to tune the stimulation with regard to the surrounded anatomy. We process a big amount of data coming from multicentric research projects and for clinicians. We provide to our users a quantitative and qualitative report but also a visual report for each subject processed, with some almost-standar views.
2. EpiPlan slicer Plug-in. We have developed a prototype to help the neurologists and anatomists of our center to plan the surgical procedure to perform intracranial EEG exploration of certain epileptic patients. We want to enhance the plug-in by adding new features and making the graphical interface and user interface interactions more robust
3. MrTrix Tracking on PyDBS.

Approach and Plan

1. Get feedback from slicer team
2. Get help for new features implementation
3. Design of news GUIs and plug-ins architectures, adding a logic for the oldest ones

Progress and Next Steps

Development of our plug-ins :

• Jordan : updating and improving post-operative Slicer plug-in in pyDBS
• Sara : planning of surgical iEEG exploration procedure for epilepsy

Discussions about developments :

• Csaba and Andras : how to use SegmetEditorLogicalEffect in python to intersect segments
• Steve : markups and reformat problems

Discussions about dissemination of our modules:

• Jean-Christophe Fillon-Robin, about Girder, that could be used to develop a web server
• Csaba Pinter, about the development of a Slicer solution dedicated to Stereotaxy (build and custom options)
• Steve Pieper, about dissemination of our stereotaxy modules, as an extension or a Slicer solution, about QMenta Discussions about our projects:
• Lauren O’Donnell, about Slicer DMRI and how to use her atlas to map fiber tracts inside the basal ganglia in parkinsonian patients, and use this for anatomo-functional studies
