1. A system, comprising:
a current source generator; and
a processor, configured to drive the current source generator to supply, for application to tissue of a subject, an electric current having an amplitude that varies in accordance with a predefined function of time, such that the amplitude initially monotonically increases to a maximum value,
wherein the processor is configured to adjust the amplitude of the electric current responsively to an estimated maximum subsurface temperature after the amplitude reaches the maximum value.
