Abstract:
(EN) The present invention provides an apparatus and a method of compensating for signal distortion of a magnetic resonance spectroscopic imaging (MRSI) or a magnetic resonance spectroscopy (MRS). According to the present invention, the method for compensating for magnetic resonance spectroscopic signal distortion comprises: a first reference signal measuring step of acquiring an additional reference signal immediately after a water signal suppression RF signal is acquired; a second reference signal measuring step of acquiring an additional reference signal immediately after a first excitation RF signal is acquired; and a step of compensating for distortion of a final data signal by using the reference signal immediately after the water signal suppression RF signal is acquired and the reference signal immediately after the first excitation RF signal is acquired. The present invention can compensate for the distortion of the final signal without an additional acquisition time for a reference water signal when MRS or MRSI data is acquired.
(FR) La présente invention concerne un appareil et un procédé de compensation de la distorsion d'un signal d'une imagerie spectroscopique par résonance magnétique (ISRM) ou d'une spectroscopie par résonance magnétique (SRM). Selon la présente invention, le procédé destiné à compenser la distorsion d'un signal spectroscopique par résonance magnétique comprend : une première étape de mesure de signal de référence consistant à acquérir un signal de référence supplémentaire immédiatement après l'acquisition d'un signal RF de suppression de signal d'eau ; une seconde étape de mesure de signal de référence consistant à acquérir un signal de référence supplémentaire immédiatement après l'acquisition d'un premier signal RF d'excitation ; et une étape consistant à compenser la distorsion d'un signal de données final à l'aide du signal de référence immédiatement après l'acquisition du signal RF de suppression de signal d'eau et du signal de référence immédiatement après l'acquisition du premier signal RF d'excitation. La présente invention peut compenser la distorsion du signal final sans temps d'acquisition supplémentaire destiné à un signal d'eau de référence lorsque des données de SRM ou d'ISRM sont acquises.
