Image intensity correction in magnetic resonance imaging

A method of medical imaging, wherein the method comprises:

• receiving initial magnetic resonance imaging data;
• receiving an image segmentation comprising the one or more anatomical regions within the magnetic resonance imaging data in response to inputting the initial magnetic resonance imaging data into an image segmentation algorithm wherein the image segmentation algorithm is configured to output the one or more predetermined anatomical regions within initial magnetic resonance imaging data descriptive of a predetermined field of view of a subject;
• selecting at least one of the one or more anatomical regions as a selected image portion using a predetermined criterion;
• and
• reducing image intensity within the selected image portion to provide intensity corrected magnetic resonance imaging data, such that anatomical structures within the selected image portion are still visible, wherein the image intensity within the selected image portion is reduced using a spatially varying weighting factor wherein the spatially varying weighing factor is smooth, and wherein the spatially varying weighting factor comprises a smooth transition at a boundary of the selected image portion.

A computer program comprising machine executable instructions stored on a non-transitory computer readable medium for execution by a computational system, wherein execution of the machine executable instructions causes the computational system to:

• receive initial magnetic resonance imaging data;
• receive an image segmentation comprising the one or more anatomical regions within the magnetic resonance imaging data in response to inputting the initial magnetic resonance imaging data into an image segmentation algorithm, wherein the image segmentation algorithm is configured to output one or more predetermined anatomical regions for initial magnetic resonance imaging data descriptive of a predetermined field of view of a subject;
• select at least one of the one or more anatomical regions as a selected image portion using a predetermined criterion;
• and
• reduce image intensity within the selected image portion to provide intensity corrected magnetic resonance imaging data, such that anatomical structures within the selected image portion are still visible, wherein the image intensity within the selected image portion is reduced using a spatially varying weighting factor wherein the spatially varying weighing factor is smooth, and wherein the spatially varying weighting factor comprises a smooth transition at a boundary of the selected image portion.
