METHOD AND CONTROL DEVICE FOR GENERATING MAGNETIC RESONANCE IMAGES

摘要

A method for acquiring raw data for generating image data of a target organ via a magnetic resonance system is described. In an embodiment, test raw data is initially acquired from a measurement region including at least the target organ using a plurality of magnetic resonance coils. Test image data is reconstructed from the test raw data. Furthermore, a mask defining the position and the dimensions of the target organ is generated using the reconstructed test image data. The magnetic resonance coils, to be used for the image acquisition, are then selected. This takes place on the basis of intensity values from a region covered by the mask and intensity values of a measurement region lying outside of the mask. Finally, the measurement is performed by acquiring raw data via the selected magnetic resonance coils. Furthermore, a device for acquiring raw data for generating image data is also described.

1. A method for acquiring raw data for the purpose of generating image data of a target organ via a magnetic resonance system, the method comprising:
acquiring test raw data from a measurement region comprising at least the target organ using a plurality of magnetic resonance coils; reconstructing test image data from the test raw data acquired by the plurality of magnetic resonance coils; generating a mask defining position and dimensions of the target organ with the aid of the reconstructed test image data; selecting at least one of the plurality of magnetic resonance coils, to be used for image acquisition, on the basis of intensity values from a region covered by the generated mask and intensity values of a measurement region lying outside of the generated mask for each individual magnetic resonance coil; and acquiring raw data via the selected at least one of the plurality of magnetic resonance coils.
