摘要:
The present invention is a method for magnetic resonance (MR) imaging of a region of interest 142 of an object of interest 120 to which a scanning sequence 200 comprising at least one pre-pulse 202, 204 and multiple readouts 206 is applied, comprising: Multiple readouts 206 are performed after at least one prepulse 202, 204 having various configurations that provide various image contrasts, and at least one to provide a set of reference readouts 206 using various configurations. Performing a preparatory stage including applying a scan sequence 200 times and generating a set of navigator images 210 having one navigator image 210 of a region of interest 142 for each configuration of the reference readout 206; Region of interest for each scan sequence 200 by applying the scan sequence 200 times 42. performing an inspection phase including the step of generating at least one image 212 of 42; and comparing at least one image 212 of the scanning sequence of the inspection phase with a navigator image 210 having the same configuration as the comparison image 212 Determining a motion of the object 120, performing a motion correction of the at least one image 212 based on the determined motion of the object of interest 120 in the at least one image 212, and based on the image 212 after performing the motion correction. Providing an MR scan 214 of the region of interest 142 of the object of interest 120. The present invention also includes an MR imaging system 110 adapted to perform the above method and a software package for upgrading the MR imaging system 110 including instructions for controlling the MR imaging system 110 according to the above method. provide.本発明は、少なくとも1回の前パルス202、204及び複数回の読出し206を含む走査シーケンス200が適用される関心対象120の関心領域142の磁気共鳴(MR)撮像のための方法であって、様々な画像コントラストをもたらす様々な構成を有する少なくとも1回の前パルス202、204後に複数回の読出し206が行われ、様々な構成を使用して1組の基準読出し206を提供するために少なくとも1回の走査シーケンス200を適用するステップ、及び基準読出し206の構成ごとに関心領域142の1つのナビゲータ画像210を持つ1組のナビゲータ画像210を生成するステップを含む準備段階を行うステップと、少なくとも1回の走査シーケンス200を適用することにより走査
