Homogenous magnetization field generation system for energizing spatial examination volume of magnetic resonance installation has several resonator segments and control and evaluation circuit

摘要

The individual resonator circuits are electromagnetically decoupled from each other according to a set of predetermined segment specific excitation parameters. There is a body coil with resonance segments surrounding the spatial examination volume and generating magnetic fields (M1-M3). A first power pulse (S1) is applied to selected first terminals (11) for warming hot-spots and is followed by a second pulse (S2) applied to further terminals (12). A third pulse (S3) is applied to third terminals (13).
