Abstract
A magnetic resonance imaging apparatus includes a generation unit configured to generate a magnetic field, a reconstruction unit configured to reconstruct an image for a subject on the basis of a magnetic resonance signal radiated from the subject in the magnetic field, a presumption unit configured to presume a distribution of an image quality deterioration degree occurring in the image on the basis of a precision at which the generation unit generates the magnetic field, and a creation unit configured to create a display image showing the distribution of the image quality deterioration degree on the image.

A magnetic resonance imaging apparatus comprising:
- a generation unit configured to generate a magnetic field;
- a reconstruction unit configured to reconstruct an image for a subject on the basis of a magnetic resonance signal radiated from the subject in the magnetic field;
- a presumption unit configured to presume a distribution of an image quality deterioration degree occurring in the image on the basis of a precision at which the generation unit generates the magnetic field;
- and
- a creation unit configured to create a display image showing the distribution of the image quality deterioration degree on the image.
A magnetic resonance imaging apparatus comprising:
- a generation unit configured to generate a magnetic field;
- a presumption unit configured to presume a distribution of an image quality deterioration degree occurring in an image on the basis of a precision at which the generation unit generates the magnetic field;
- a determination unit configured to determine an inappropriate region having an image quality deterioration of which a degree exceeds an allowable level on the basis of the distribution of the image quality deterioration degree;
- a setting unit configured to set an imaging region, which is a target for reconstructing a medical diagnostic image for a subject, in accordance with an operator's instruction;
- an information unit configured to inform the operator of a fact that the imaging region includes the inappropriate region;
- and
- a reconstruction unit configured to reconstruct an image for the subject on the imaging region on the basis of a magnetic resonance signal radiated from the subject in the magnetic field.
A magnetic resonance imaging method comprising the steps of:
- generating a magnetic field;
