ielu

ielu automates sorting, labeling, registration, and localization of intracranial electroencephalography (iEEG) subdural grid electrodes in CT and MR images to support accurate electrode identification for clinical and research applications.

Key Features:

• Automated Sorting and Labeling: Automatically sorts and labels electrodes from subdural grids using their known geometric configurations.
• Full Pipeline Integration: Implements a complete pipeline for registration, localization, and labeling of iEEG electrodes in CT and MR images.
• Validation and Accuracy: Validated against manual inspection across twelve subjects with medically intractable epilepsy, achieving a 96% correct electrode identification rate.

Scientific Applications:

• Epilepsy presurgical evaluation: Supports electrode management for patients with medically intractable epilepsy undergoing iEEG monitoring.
• iEEG data collection and analysis: Facilitates precise identification of electrodes from subdural grids to improve accuracy of diagnostic and treatment-planning analyses.

Methodology:

Leverages known geometrical configurations of subdural grids to automate sorting and labeling and performs registration and localization of electrodes in CT and MR images.
