Title (EN) REDUCTION OF MOTION ARTIFACT IN NMR IMAGES USING SPHERICAL NAVIGATOR SIGNALS
(FR) REDUCTION DES ARTEFACTS DE DEPLACEMENT DANS DES IMAGES OBTENUES PAR RESONANCE MAGNETIQUE NUCLEAIRE GRACE A L'UTILISATION DE SIGNAUX DE NAVIGATEUR SPHERIQUES
Abstract: front page image
(EN)A series of fMRI image frames are acquired along with interleaved navigator signals. The navigator signals are acquired while three orthogonal readout gradients are applied such that a spherical surface is sampled in k-space. The navigator signals are analyzed to measure subject rotational and translational motion during the scan.
(FR)Selon l'invention, une série d'images obtenues par imagerie par résonance magnétique fonctionnelle sont saisies en même temps que des signaux de navigateur imbriqués. Les signaux de navigateur sont saisis tandis que trois gradients de sortie orthogonaux sont appliqués de sorte qu'une surface sphérique soit échantillonnée dans l'espace k. Les signaux de navigateur sont analysés pour permettre la mesure du déplacement en rotation et en translation du sujet pendant le balayage.
