Patient-specific solution of the electrocorticography forward problem in deforming brain

Image data and computational grids for computing brain shift and solving the electrocorticography forward problem

“… The dataset [2] described in this paper was used in our recently published study on the solution of the intracranial electroencephalography (iEEG) or electrocorticography (ECoG) forward problem in a deforming brain [1] . The data can be used to replicate the results of that study or for comparison with other modeling strategies in subsequent studies.…”

“…This article provides the data [2] used to solve the electrocorticography problem in a deforming brain, as reported in the study published by Zwick et al. [1] . The data can be used to replicate the results therein or to develop and test alternative methods.…”

“…For comparison of different modeling approaches in our recent study described in the related article [1] , we created the following three models: Unwarped : A model representing the unwarped brain geometry extracted from the preoperative (unwarped) image data. This model has the actual electrode positions identified from postoperative CT. Projected : An unwarped geometry model with projected electrode positions.…”

“…For the unwarped geometry model, we also compared results obtained using MRI segmentation conducted with STAPLE and our DTI-based tissue classification method [1] .…”

“… This article describes the dataset applied in the research reported in NeuroImage article “Patient-specific solution of the electrocorticography forward problem in deforming brain” [1] that is available for download from the Zenodo data repository ( https://zenodo.org/record/7687631 ) [2] . Preoperative structural and diffusion-weighted magnetic resonance (MR) and postoperative computed tomography (CT) images of a 12-year-old female epilepsy patient under evaluation for surgical intervention were obtained retrospectively from Boston Children's Hospital.…”
