Intra-blade filter for motion corrected magnetic resonance data

摘要

In an embodiment, a method includes processing magnetic resonance (MR) data according to a process including applying a density filter to blades of k-space data rotated about a section of k-space. Each blade may include a first set of encode lines weighted in a first signal weighting and a second set of encode lines weighted in a second signal weighting. The density filter may be configured to preferentially weight each blade in the first signal weighting to produce blades of weighted k-space data.

1. A method, comprising:
processing magnetic resonance (MR) data according to a process comprising:
applying a density filter to blades of k-space data rotated about a section of k-space, each blade comprising a first set of encode lines weighted in a first signal weighting and a second set of encode lines weighted in a second signal weighting; and wherein the density filter is configured to preferentially weight each blade in the first signal weighting to produce blades of weighted k-space data, and wherein the blades comprise centric encoding such that the first set of encode lines correspond to the center of each blade, cross a central region of k-space, and are acquired before the second set of encode lines, and wherein the first signal weighting corresponds to T1-weighting or proton density weighting and the second signal weighting corresponds to T2 and/or T2*-weighting.
