Title:
磁気共鳴イメージングにおける歪み補正方法及び装置
Document Type and Number:
Japanese Patent JP5594971
Kind Code:
B2
Abstract:
In a method and apparatus for correcting distortion during magnetic resonance imaging k space data in a number of readout encoding directions, sampling points on the phase encoding lines are primarily in low frequency regions of k space and the number of such sampling points is less than that of all sampling points. A view angle tilting compensation gradient is superimposed on the axis of a layer selection gradient. The k space data acquired from the number of directions are then combined.
