Abstract

In this work a comparison of two passive decoupling techniques for ultra-high field magnetic resonance imaging (MRI) is presented. An electromagnetic band-gap (EBG) structure and a single passive dipole are compared in terms of their capabilities to decouple two active dipole body array elements at 7 Tesla at an extremely short inter-element distance. Decoupling band as well as distribution of circularly polarized radiofrequency magnetic field inside a homogeneous phantom provided with these two techniques are compared.
