METHOD AND APPARATUS FOR ACQUIRING A MAGNETIC RESONANCE IMAGE DATA SET AND MAGNETIC RESONANCE DEVICE

摘要

In a method and apparatus for acquiring a magnetic resonance image data set of a scan area of an examination subject, the image data are acquired with a magnetic resonance apparatus having a transmitter coil that emits a radio-frequency signal having at least two transmission channels so that different polarizations of the radio-frequency signal are produced, and a magnetic resonance sequence is used to acquire raw data for the magnetic resonance image data set, wherein raw data are acquired during at least two scanning operations with the magnetic resonance sequence, with different polarizations of the radio-frequency signals being used for at least two of the at least two scanning operations, following which the magnetic resonance image data set is determined by averaging the raw data.

1. A method for acquiring a magnetic resonance (MR) image data set, comprising:
operating an MR scanner comprising a transmitter coil, while an examination subject is situated in said MR scanner, to emit a radio-frequency signal from said transmitter coil that emits a radio-frequency signal with multiple, different polarizations of said radio-frequency signal in a volume of the examination subject; operating the MR scanner according to a magnetic resonance sequence comprising at least two scan operations in which said different polarizations of said radio-frequency signals are respectively produced, and acquiring a respective set of raw MR data in the respective two scan operations; and providing the respective sets of raw data to a computer and, in said computer, producing a magnetic resonance image data set by averaging the sets of raw data, and making said magnetic resonance image data set available in electronic form as a data file.
