BACKGROUND

Field

The present disclosure relates to a method for generating at least one magnetic resonance (MR) image, to an MR system configured to generate the at least one MR image, to a computer program and a carrier.

Related Art

To accelerate magnetic resonance (MR) measurements, it is known to use undersampling schemes when acquiring the MR signals in k-space. Here, depending on the acceleration factor of the undersampling scheme, data samples are only taken for every second or third k-space position. Then a reconstruction of the undersampled MR data set can be implemented to obtain a reconstructed MR data set, the MR image.

In this context, an image acquisition method called CAIPIRINHA is known. Furthermore, a method known as WAVE-CAIPI was introduced by Bilgic B. et al., as described in “WAVE-CAIPI for highly accelerated 3D imaging” Magnetic Resonance Imaging 73(6) 2015:2152-2162.

If the acceleration factor is too high the reconstructed magnetic resonance image (MRI) data set can show artefacts and/or noise.

WAVE-CAIPI applies identical oscillating readouts on one of the two axes perpendicular to the read-out direction which creates constant radii corkscrew trajectories through k-space for each acquired line. Accelerating scan times by increasing undersampling of WAVE-CAIPI acquisitions results in poor images with high g-factors. To avoid artefacts resulting in poor image quality, undersampling is normally limited to less than 3×3.

Furthermore, the patient as object under examination hears an unpleasant high-pitched sound of approximately constant 100 dB in view of the occurring gradient switching.
