We present a detailed retrospective study on clinical epilepsy patient data, showing the potential advantage of following a curved path in the brain for both insertion and ablation purposes. Curved trajectories that follow the contours of given anatomy, as the amygdala-hippocampal complex (AHC) in the case of refractory epilepsy, were associated with a statistically significant improvement compared to their straight counterpart. Benefits were measured in terms of several quantitative metrics including percentage coverage of the ablation region and a published risk score to quantify, among other aspects, the safe distance between the ablation trajectory and critical brain regions. read more
