摘要：

Three-dimensional computer simulations of a patient under consideration for heating by the BSD Sigma 60 phased array applicator showed marked specific absorption rate (SAR) enhancement in the region where there was a concentration of metallic surgical clips. Subsequent tests in tissue-equivalent phantom material confirmed that metallic objects much shorter than the wavelength in tissue of the radiative electromagnetic field can cause significant changes in the power deposition near the implanted metal. The placement of extensive number of surgical clips may therefore hinder the ability to subsequently utilize radiative electromagnetic heating modalities.
