Abstract

Es wird ein Verfahren zur Erzeugung von Magnetresonanzaufnahmen eines Untersuchungsobjekts (P) beschrieben, bei dem am Untersuchungsobjekt zur lokalen Beeinflussung der B¶1¶-Feldverteilung ein dielektrisches Element (1) positioniert wird, welches ein Relaxationsagens enthält. Das Relaxationsagens umfasst dabei vorzugsweise eine paramagnetische Substanz. Darüber hinaus werden ein entsprechendes dielektrisches Element (1) sowie die Verwendung eines solchen dielektrischen Elements (1) zur Homogenisierung des B¶1¶-Feldes beschrieben.
