Comparison of (a) power dissipation and (b) coil heating of conventional monophasic cosine TMS and cTMS, based on data from Table III. All values are normalized to those for Magstim 200. Pulse amplitude is directly proportional to initial capacitor voltage V_C0. Power dissipation is directly proportional to energy used per pulse ΔW_C. Coil heating is directly proportional to load integral ${\displaystyle {\int }_0^{t_P}{I}_L^2\text{dt}}$. Note that all data points correspond to TMS configurations that yield same amount of neuronal depolarization, and therefore pulses with larger amplitude have briefer PW (refer to Table III).
