PROBLEM TO BE SOLVED: To provide a device for MRI of a body placed in an examination volume.SOLUTION: A device 1 comprises means 2 for establishing a substantially homogeneous main magnetic field in an examination volume, means 3, 4, 5 for generating switched magnetic field gradients superimposed upon the main magnetic field, means 6 for irradiating a body with RF pulses, means 12 for controlling the generation of the magnetic field gradients and the RF pulses, means 10 for receiving and sampling MR signals, and reconstruction means 14 for forming MR images from the signal samples. According to one aspect, the device 1 is arranged to weight acquired MR data, where weighting factors are computed on the basis of acquisition times for contrast manipulation, correlation measures for motion compensation, and the geometry of overlapping areas of k-space blades.COPYRIGHT: (C)2015,JPO&INPIT【課題】検査容積内に配置された身体のMRI用装置を提供する。【解決手段】装置1は、検査容積内に実質的に均一な主磁場を構築する手段2、主磁場に重畳される切替え磁場傾斜を生成する手段3、4、5、身体にRFパルスを放射する手段6、磁場傾斜及びRFパルスの生成を制御する手段12、MR信号の受信及び標本化を行う手段10、及び信号標本からMR画像を形成する再構成手段14を有する。一態様によれば、装置1は収集MRデータを重み付け、重み係数がコントラスト操作に関する収集時間、動き補償に関する相関量、及びk空間ブレードの重なり領域の幾何学配置に基づいて計算される。【選択図】図1
