Abstract

Buluşa göre, MRG uyumlu bir elektrot devre yapısı sağlanmıştır. Yapı, bir elektrot telinden üretilmiş en az iki filtre bileşeni içerir. Bir filtre bileşeni, teldeki RF kaynaklı akımın elektrot vasıtasıyla telden çıkmasını etkili bir şekilde engelleyerek yetersiz zayıflatma sorununu gideren, bir elektrodun yakınına konumlandırılmış tek veya birden çok katmanlı bir rezonant LC filtresi olabilir. İkinci filtre bileşeni, elektrot telinin uzunluğu boyunca konumlanmış, rezonant LC filtresinin aşırı ısınma sorununu, telde indüklenen akımı rezonant LC filtresine ulaşmadan önce önemli ölçüde zayıflatarak gideren bir veya birden çok rezonans yapmayan filtre içerebilir. Rezonant LC filtresi, rezonans yapmayan filtrelerin sonunun uzağına da yerleştirilebilir.
