Abstract

In the above-named work by G. Sergiadis et al. (see ibid., vol.7, p.381-5, 1988), an exact solution to the electromagnetic field distribution inside a conductive cylinder of finite length was proposed for estimation of the thermal losses in biological tissues under MRI conditions. The commenters claim to show that such a solution is untrue for a finite-length cylinder, and that the related numerical treatments in the work of Sergiadis et al. are for an infinite cylinder, not a finite cylinder.
