eTMS Ramp Planner + 10–20 Head Map

Step 1 — Measurements (10–20 system)

Nasion–Inion (cm)

Used for Cz and Fz.

Preauricular–Preauricular (cm)

Used for C3/C4 offset from Cz.

Motor Threshold (%)

Start = 40% MT · Mid = 60% MT · Goal = 80% MT (rounded HALF-UP to whole %)

Cz (cm)

—

Place sticker at Cz.

Fz offset (cm from Nasion)

—

Reference for frontal midline (Fz).

C3/C4 offset (cm from Cz)

—

Place stickers at C3 & C4 symmetrically from Cz.

Step 2 — Intensities (rounded HALF-UP to whole %)

Start Intensity

—%

= round( 40% × MT )

Split (Mid)

—%

= round( 60% × MT )

Goal Intensity

—%

= round( 80% × MT )

Step 3 — Session 1 update intervals

Chips show train/30 → %. Last 3 trains hold the split (mid) intensity.

Step 3 — Session 2 update intervals

Begins at the same displayed % where Session-1 ends. Last 3 trains hold the goal intensity.
