Title:
磁気共鳴断層撮影の拡散強調画像のためのマルチショット方法
Document Type and Number:
Japanese Patent JP4832786
Kind Code:
B2
Abstract:
In a multi-shot method for diffusion-weighted imaging in magnetic resonance tomography, the sampling of the k-matrix in the readout direction ensues in segments, and immediately after acquisition of an image data set by readout of one segment by means of echo signals, a navigation data set is acquired by readout of the middle region of the k-matrix at virtually the same time. A movement-corrected diffusion-weighted MRT image is generated by combining of the image data sets with the corresponding navigation data sets and subsequent Fourier transformation.
