Temperature distribution of whole body with a cardiac
pacemaker by the low frequency band of the gradient
magnetic field generated by the Helmholtz coils were
simulated by low frequency solver and thermal simulator
with steady state solver. Simulations were performed by
40mT/s of slew late and from 100Hz to 2500Hz of
frequency of gradient magnet fields. Temperature near
the center of the element of Helmholtz coil were higher
and maximum temperature was 6.83e-03℃ at 1000Hz. The
temperature around a cardiac pacemaker was less than
1.74e-04℃ at 1000Hz. The results leaded there was little
substantial risk for heating in this case.
