Title:
MULTI-ECHO MRI USING REPEATED SAMPLING OF K-LINES WITH DIFFERENT SEQUENTIAL ORDER PER REPETITION
Document Type and Number:
WIPO Patent Application WO/2015/181091
Kind Code:
A3
Abstract:
The invention relates to a method of MR imaging of at least an object (10) placed in an examination volume of a MR device (1). It is an object of the invention to enable fast MR imaging using a multi-echo imaging technique which is robust with respect to motion. The method of the invention comprises the steps of: - generating echo signals by subjecting the object (10) to an imaging sequence, - acquiring the echo signals, each echo signal being attributed to a k-space line, wherein a number of k-space lines, which are adjacently arranged in a part of k-space, are repeatedly sampled, with said number of k-space lines being sampled in a different sequential order per repetition, and - reconstructing a MR image from the acquired echo signals. Moreover, the invention relates to a MR device for carrying out this method as well as to a computer program to be run on a MR device.
