Figure Lengend Snippet: Experimental arrangement of test articles for simultaneous assessment of radiofrequency‐induced heating in simulation of an implant. (a) Picture showing arrangement of depth electrodes along the left–right axis and perpendicular to the sagittal plane, with the 16‐contact standard sEEG (ID# 2101‐16‐091) and 16‐contact RF ablation (ID# 2102‐16‐291) depth electrodes placed parallel to one another on the left side of the phantom ‘head’, and the 10‐contact depthalon (ID# 2102‐10‐084) and 8‐contact macro‐/16‐contact microwire (ID# 2104‐16‐16‐001) depth electrodes placed parallel to one another on the right; the subdural grid and strip electrodes were placed flat onto the mesh along the cranio‐caudal axis, with the tails oriented cranially in a configuration that simulated implants recording from the cortical surface. (b) Locations of the four MRI‐compatible fluoroptic thermometer probes. Probe #4 was placed just beyond the neck region of the phantom and was used as the reference; probe #1 was placed at the most distal contact (contact #1) of the 16‐contact standard eEEG depth electrode (2102‐16‐091); probe #2 was positioned on the most distal contact (contact #1) of the 16‐contact RF ablation depth electrode (ID# 2102‐16‐291); probe #3 was positioned on the corner contact (contact #48) of the 64‐contact grid electrode (ID# 2110‐64‐042).

Article Snippet: Continuous temperature measurements were made simultaneously from four positions using an MRI‐compatible fluoroptic thermometer (Model 3100; Luxtron Corporation, Santa Clara, CA, USA; accuracy ±0.1°C; SMM probes with 0.3 × 0.3 × 0.3 mm 3 sensors).
