Magnetic resonance antenna arrangement and method for acquiring magnetic resonance signals using the magnetic resonance antenna arrangement

摘要

A magnetic resonance antenna arrangement having a plurality of antenna elements disposed around a measurement chamber and a plurality of switching elements is provided. The antenna elements and the switching elements are disposed and interconnected such that in a first switching configuration of the switching elements, the antenna elements form a first antenna architecture, and in a second switching configuration of the switching elements, the antenna elements form a second antenna architecture.
