METHOD AND APPARATUS FOR MAGNETIC RESONANCE IMAGING WITH A MUSIC-BASED GRADIENT CURVE

摘要

In a method and apparatus for magnetic resonance imaging with a music-based gradient curve, a magnetic resonance sequence and a piece of music are provided to a controller of a magnetic resonance apparatus. The piece of music is modified in the controller by taking into account at least one acoustic resonance parameter that characterizes at least one acoustic resonance frequency of the magnetic resonance apparatus, so a modified piece of music is generated. A gradient curve of the magnetic resonance sequence is adjusted using the modified piece of music, so an adjusted magnetic resonance sequence is generated. Magnetic resonance image data of the examination object is acquired by operation of the apparatus with of the adjusted magnetic resonance sequence.

1. A method for acquiring magnetic resonance (MR) raw data, comprising:
providing a processor with an MR data acquisition sequence for operating an MR scanner, said MR scanner comprising a gradient coil system and said MR data acquisition sequence comprising a gradient curve that operates said gradient coil system, said MR scanner having at least one acoustic resonance frequency; also providing said processor with a piece of music; in said processor, modifying said piece of music dependent on at least one acoustic resonance parameter that characterizes said at least one acoustic resonance frequency of said MR scanner, thereby producing a modified piece of music; using said modified piece of music in said processor to adjust said gradient curve in said MR data acquisition sequence, thereby producing an adjusted MR data acquisition sequence; and operating said MR scanner according to said adjusted MR data acquisition sequence, while an examination object is situated in the MR scanner, to acquire MR raw data from the examination object.
