Image processing apparatus, magnetic resonance imaging apparatus, and storage medium

An image processing apparatus, comprising:

• a processing circuitry configured to:
• obtain an input image related to a brain;
• divide a region of the brain in the input image, into plural regions;
• set a parameter value to generate a calculated image related to the brain, such that a relation of contrast among regions included in the plural regions in the calculated image becomes a relation of contrast among the regions, the relation being predetermined for an image type of the calculated image or for a disease of the subject;
• and
• generate the calculated image by using the input image and the set parameter value.

A magnetic resonance imaging apparatus, comprising:

• a processing circuitry configured to:
• divide a region of a brain in a magnetic resonance (MR) image related to the brain, into plural regions;
• set a parameter value to generate a calculated image related to the brain by synthetic MRI, such that a relation of contrast among regions included in the plural regions in the calculated image becomes a relation of contrast among the regions, the relation being predetermined for an image type of the calculated image or for a disease of the subject;
• and
• generate the calculated image by the synthetic MRI, by using a quantitative image derived from the MR image, and the set parameter value.

A non-transitory computer-readable storage medium having plural computer-executable commands recorded therein, the plural computer-executable commands causing the computer to execute:

• obtaining a magnetic resonance (MR) image acquired by a magnetic resonance imaging apparatus, the MR image being related to a brain;
• dividing a region of the brain in the MR image, into plural regions;
• setting a parameter value to generate a calculated image related to the brain by synthetic MM, such that a relation of contrast among regions included in the plural regions in the calculated image becomes a relation of contrast among the regions, the relation being predetermined for an image type of the calculated image or for a disease of the subject;
• and
• generating the calculated image by the synthetic MRI, by using a quantitative image derived from the MR image, and the set parameter value.
