MAGNETIC RESONANCE IMAGING APPARATUS WITH SEGMENTED DATA ACQUISTION

摘要

To provide an imaging technique suitable for acquiring an image with reduced artifacts due to differences in signal intensity. An MR apparatus 100 acquires, in data acquisition periods A1, A2, and A3, data at part of grid points lying closer to a high-frequency region RH within a low-frequency region RL, and data at part of grid points lying closer to the low-frequency region RL within the high-frequency region RH. On the other hand, in a data acquisition period B, it acquires data at another part of grid points lying closer to the high-frequency region RH within the low-frequency region RL, and data at another part of grid points lying closer to the low-frequency region RL within the high-frequency region RH.

主权项

1. A magnetic resonance apparatus comprising scanning section configured to conduct a scan for acquiring data at grid points contained in a first region in k-space and data at grid points contained in a second region adjacent to said first region, wherein said scanning section acquires:
in a first data acquisition period in which acquisition of data at grid points in k-space is conducted, data at part of a first plurality of grid points lying closer to said second region within said first region, and data at part of a second plurality of grid points lying closer to said first region within said second region, and in a second data acquisition period in which acquisition of data at grid points in k-space is conducted, data at grid points of said first plurality of grid points other than those at which data are acquired in said first data acquisition period, and data at grid points of said second plurality of grid points other than those at which data are acquired in said first data acquisition period.
