This study introduces a novel strategy to correct spatial errors in image-guided neurosurgery caused by brain deformation. The method updates preoperative imaging using intraoperative data, improving surgical accuracy.

Area of Science:

Neurosurgery
Medical Imaging
Computational Anatomy

Background:

Image-guided neurosurgery relies on preoperative scans, which can be inaccurate due to intraoperative brain shifts.
Brain deformation during surgery leads to spatial errors, compromising navigation accuracy.
