New Paper! Super-resolution for localizing electrode grids as small, deformable objects during epilepsy surgery using augmented reality headsets

We’re excited to share our latest publication in the International Journal of Computer Assisted Radiology and Surgery (presented at IPCAI 2025 17-18th June): “Super-resolution for localizing electrode grids as small, deformable objects during epilepsy surgery using augmented reality headsets”.

AR + AI pipeline for ioECoG localization

In this work, they (first author Hizirwan S. Salim (SURF) with co-authors, in particular, Abdullah, Theo, and Mohamed from the BIGR) present a feasibility study that localizes intra-operative ECoG (ioECoG) electrode grids using an augmented-reality head-mounted display combined with AI.

The paper addresses the challenge of pose estimation of relatively small objects, difficult to detect using low resolution cameras of head-mounted displays, by using super-resolution models trained on synthetically rendered data of an ioECoG grid, a device used during epilepsy surgery.

This work is available open access in IJCARS (DOI: 10.1007/s11548-025-03401-5).
