Abstract
A data processing apparatus includes processing circuitry configured to: acquire data that are based on a magnetic resonance signal acquired from a specific region of an object, the data being acquired for detecting a chemical shift of substance; and perform relation calculation between a designated chemical shift arbitrarily designated in a predetermined range of the chemical shift and displacement amount of a position of the specific region displaced due to the designated chemical shift, as position correction data.
Claims16
A data processing apparatus, comprising:
- processing circuitry configured to:
- acquire magnetic resonance signal data acquired from a specific region of an object, the data being obtained for detecting a chemical shift of a substance;
- perform a relation calculation between a designated chemical shift, which is arbitrarily within a predetermined range of the chemical shift and a displacement amount of a position of the specific region that is displaced due to the designated chemical shift;
- and
- generate position correction data to correct positional shift amounts corresponding to the designated chemical shift.
An MRI apparatus, comprising:
- processing circuitry configured to
- acquire magnetic resonance signal data acquired from a specific region of an object, the data being obtained for detecting a chemical shift of a substance;
- perform a relation calculation between a designated chemical shift, which is arbitrarily within a predetermined range of the chemical shift and a displacement amount of a position of the specific region that is displaced due to the designated chemical shift;
- and
- generate position correction data to correct positional shift amounts corresponding to the designated chemical shift;
- a display;
- and
- a user interface,
- wherein the processing circuitry is further configured to cause the display to display a magnetic resonance image of the object and a spectral image that indicates the chemical shift on one axis and indicates a signal intensity on another axis, and
- the user interface is configured to designate the chemical shift on the spectral image displayed on the display.
An MRI apparatus, comprising:
- processing circuitry configured to
- acquire magnetic resonance signal data acquired from a specific region of an object, the data being obtained for detecting a chemical shift of a substance;
- perform a relation calculation between a designated chemical shift, which is arbitrarily within a predetermined range of the chemical shift and a displacement amount of a position of the specific region that is displaced due to the designated chemical shift;
- and
- generate position correction data to correct positional shift amounts corresponding to the designated chemical shift,
- wherein the processing circuitry is further configured to
- cause a display to display a magnetic resonance image of the object,
- calculate a position of an effective ROI corresponding to the designated chemical shift, and
- cause the display to display the effective ROI in such a manner that the effective ROI is superimposed on the magnetic resonance image.
