Improving Mri Surface Coil Decoupling To Reduce B1 Distortion, Christian K. Larson
Improving Mri Surface Coil Decoupling To Reduce B1 Distortion, Christian K. Larson
Theses and Dissertations
As clinical MRI systems continue to advance, larger focus is being given to image
uniformity. Good image uniformity begins with generating uniform magnetic fields, which
are easily distorted by induced currents on receive-only surface coils. It has become an
industry standard to combat these induced currents by placing RF blocking networks on
surface coils. This paper explores the effect of blocking network impedance of phased array surface coils on B1 distortion. It has been found and verified, that traditional approaches for blocking network design in complex phased arrays can leave undesirable B1 distortions at 3 Tesla. The traditional approach of …
