Abstract
A magnetic resonance imaging method and device include a processor and a demodulator including a signal sampling device which provide automatic quantitative motion evaluation of a part of an object. Pulse and gradient sequences (tsq) are applied in pairs with spatially differing tagging patterns, images corresponding to the pairs being subtracted so as to form a tagged image. The motion is monitored by scanning of the tagging pattern in the tagged image which permits improved motion evaluation.
