Abstract :
Conventional power-supply-cables (i.e. a pair of two parallel cables) connected with stimulation coils in magnetic stimulation have problems associated with large leakage magnetic fields and acoustic noise. We have introduced a coaxial cable power supply system to solve these problems. The coaxial cable power supply system also improves the efficiency of stimuli to 43% compared with conventional parallel conductor power-supply-cables
