DIELECTRIC ELEMENT, AND MAGNETIC RESONANCE IMAGING METHOD USING SAME

摘要

A dielectric element for positioning on an examination subject for locally influencing the B1 field distribution during magnetic resonance data acquisition contains a relaxation agent bound to mutually separated particles. The relaxation agent incorporates a paramagnetic substance. In a corresponding method for acquiring magnetic resonance data from an examination subject, such a dielectric element is positioned on the examination subject for locally influencing the B₁ field distribution, by homogenizing the B₁ field of a magnetic resonance apparatus.
