MAGNETIC RESONANCE DEVICE AND METHOD

摘要

The invention relates to a device for magnetic resonance imaging of at least a portion of a body placed in an examination volume. The device is arranged to perform the following successive steps: a) acquiring two or more differently phase-encoded MR signals (a, b, c, d) by subjecting the portion to a shot of an imaging pulse sequence comprising at least one RF pulse and switched magnetic field gradients; b) repeating step a) to scan k-space completely by applying a plurality of shots and by using a phase encoding scheme, according to which k-space is divided into at least two segments (17, 18, 19, 20), each segment (17, 18, 19, 20) being further divided into sub-segments, wherein MR signals (a, b, c, d) are acquired from different sub-segments of a single segment during each shot, which sub- segments are successively arranged in k-space in the order of the temporal succession of the MR signals (a, b, c, d), and c) reconstructing an MR image from the acquired MR signals.
