Method and apparatus for magnetic resonance imaging

1. A method for operating a magnetic resonance imaging apparatus comprising:

providing an electronic designation to a computer that selects a first recording region, which is cuboidal, of an examination subject;

in said computer, automatically determining a second recording region within said subject that is an adjustment of the first recording region, with said second recording region being cube-shaped;

embodying said second recording region in a magnetic resonance data acquisition sequence and operating a magnetic resonance scanner with said magnetic resonance sequence to acquire magnetic resonance scan data from an entirety of said second recording region;

providing said magnetic resonance scan data to an image reconstruction computer and, in said image reconstruction computer, reconstructing magnetic resonance image data from the magnetic resonance scan data; and

making an image region of the magnetic resonance image data available in electronic form as a data file from said image reconstruction computer.

2. A method as claimed in claim 1 comprising generating said magnetic resonance sequence as a magnetic resonance sequence that requires a cube-shaped recording region.

3. A method as claimed in claim 1 comprising providing, as said image region from said image reconstruction computer, an image region that maps said first recording region.

4. A method as claimed in claim 1 comprising providing, as said image region, an image region corresponding in all dimensions and in spatial positioning with said first recording region.

5. A method as claimed in claim 1 wherein said computer automatically determines said second recording region so that said first recording region is a section of said second recording region.

6. A method as claimed in claim 1 wherein said first recording region has a first extent in a first direction, as second extent in a second direction, and a third extent in a third direction, wherein said first extent is longer than said second extent and said third extent, and comprising, in said computer, adjusting said first recording region for automatic determination of said second recording region so that said second extent and said third extent are adjusted to the first extent.

7. A method as claimed in claim 6 comprising adjusting said second extent to said first extent by lengthening the second extent by a second extension factor, said second extension factor being a ratio of said first extent and said second extent.

8. A method as claimed in claim 6 comprising adjusting said third extent to said first extent by lengthening said third extent by a third extension factor that is a ratio between said first extent and said third extent.

9. A magnetic resonance apparatus comprising:

a magnetic resonance scanner;

a computer provided with an electronic designation that selects a first recording region, which is cuboidal, of an examination subject;

said computer being configured to automatically determine a second recording region within said subject that is an adjustment of the first recording region, with said second recording region being cube-shaped;

said computer being configured to embody said second recording region in a magnetic resonance data acquisition sequence and to operate the magnetic resonance scanner with said magnetic resonance sequence to acquire magnetic resonance scan data from an entirety of said second recording region;

said computer being configured to reconstruct magnetic resonance image data from the magnetic resonance scan data; and

said computer being configured to make an image region of the magnetic resonance image data available in electronic form as a data file from said computer.

10. A non-transitory, computer-readable data storage medium encoded with programming instructions, said storage medium being loaded into a control and evaluation computer of a magnetic resonance apparatus that comprises a magnetic resonance scanner, said programming instructions causing said control and evaluation computer to:

receive an electronic designation to a computer that selects a first recording region, which is cuboidal, of an examination subject;

automatically determine a second recording region within said subject that is an adjustment of the first recording region, with said second recording region being cube-shaped;

embody said second recording region in a magnetic resonance data acquisition sequence and operate a magnetic resonance scanner with said magnetic resonance sequence to acquire magnetic resonance scan data from an entirety of said second recording region;

reconstruct magnetic resonance image data from the magnetic resonance scan data; and

make an image region of the magnetic resonance image data available in electronic form as a data file from said control and evaluation computer.
