Slew Rate (G/µs)

How rapidly the magnetic field strength changes during a pulse edge. A higher slew rate means a sharper, more abrupt field change. That induces stronger electric fields in tissue. Each pulse has a rising edge and a falling edge, and the slew rate of each is reported separately because many devices ramp up and down at different speeds. Both contribute to cumulative dose (see Total Stimulation Intensity). It is measured across the fast middle of the edge, from the 10% level to the 90% level, as the field change divided by the time between those two points. That is the same way an oscilloscope gauges edge speed. Expressed in Gauss per microsecond (G/µs). The rising-edge slew rate is the same physical quantity as Peak dB/dt, framed as an engineering performance metric rather than a safety threshold.
