Apparatus and method for magnetic resonance imaging

摘要

A magnetic resonance imaging apparatus includes: a sequence controlling unit that, by controlling an execution of a pulse sequence, acquires magnetic resonance (MR) signals corresponding to a plurality of channels in the pulse sequence executed as a series, the MR signals being configured to be arranged into a first region of a k-space at first intervals and into a second region larger than the first region at second intervals larger than the first intervals; an arranging unit that arranges the MR signals corresponding to the channels into the k-space as k-space data; and an image generating unit that generates first-interval k-space data corresponding to the channels based on the second-interval k-space data acquired by executing the pulse sequence and generates a magnetic resonance image based on the generated first-interval k-space data, the first-interval k-space data acquired by executing the pulse sequence, and sensitivity distributions corresponding to the channels.

1. A magnetic resonance imaging apparatus comprising:
a sequence controlling unit configured to, by controlling an execution of a pulse sequence, acquire magnetic resonance signals corresponding to a plurality of channels in the pulse sequence executed as a series, the magnetic resonance signals being configured to be arranged into a first region of a k-space so as to be positioned at first intervals and into a second region larger than the first region so as to be positioned at second intervals larger than the first intervals; an arranging unit configured to arrange the magnetic resonance signals corresponding to the plurality of channels into the k-space as k-space data; and an image generating unit configured to generate k-space data at the first intervals corresponding to the plurality of channels based on the k-space data at the second intervals acquired by the execution of the pulse sequence and generate a magnetic resonance image based on the generated k-space data at the first intervals, the k-space data at the first intervals acquired by the execution of the pulse sequence, and sensitivity distributions corresponding to the plurality of channels.
