Embodiment Construction

[0061] figure 1 A magnetic resonance system 5 (of a magnetic resonance imaging or nuclear spin tomography system) is shown schematically. In this case, the basic field magnet 1 generates a temporally constant strong magnetic field for the polarization and alignment of the nuclear spins in the examination region of the object, for example the part of the human body to be examined. The high homogeneity of the basic magnetic field required for the nuclear spin resonance measurement is defined in the spherical measurement space M into which the part of the human body to be examined is introduced. In order to support the homogeneity requirements and in particular to eliminate temporally invariable influences, so-called shims made of ferromagnetic material are installed at suitable locations. Time-variable influences are eliminated by shim coils 2 .

[0062] A cylindrical gradient coil system 3 consisting of three partial coils is used in the basic field magnet 1 . Each partial c...

Abstract

The invention relates to a method for generating MR images and an appropriately designed magnetic resonance system. An embodiment of the invention relates to the generation of MR images of a volume section within an examination object by way of a magnetic resonance scanner (5). In at least one embodiment, the following steps are performed: (S2) generating at least one of the MR images; (S4) automatically performing a number of quality inspections on the at least one MR image; and, (S6) should one of these quality inspections fail, an action is automatically performed in order to improve a quality when generating more of the MR images.

Description

technical field [0001] The invention relates to a method for generating MR images which are produced by means of a magnetic resonance system and are of good quality. Furthermore, the invention describes a correspondingly designed magnetic resonance system as well as a corresponding computer program product and a corresponding electronically readable data carrier. Background technique [0002] According to the prior art, during an examination of a patient by means of a magnetic resonance system, the image quality of the MR images created here is checked manually after the examination and if the image quality falls below an acceptable level, a corresponding change is then made. This change includes, on the one hand, changing the protocol in which the corresponding parameters for the acquisition of the MR images are predetermined, and on the other hand, changing the strategy (measurement method) for acquiring the MR images. However, a manual check of the quality of the MR imag...
