Abstract
A computer-implemented system and method of determining anterior commissure (AC) and posterior commissure (PC) points in a volumetric neuroradiological image. The method includes determining, by a computer, a mid-sagittal plane estimate to extract a mid-sagittal plane image from the volumetric neuroradiological image, and AC and PC point estimates in the mid-sagittal plane image. The method further includes determining, by the computer, a refined mid-sagittal plane estimate from the AC and PC point estimates to extract a refined mid-sagittal plane image, the AC point from the refined mid-sagittal plane image, and the PC point from the refined mid-sagittal plane image and the AC point.
Claims21
1-20. (canceled)
A method for processing an image, the method comprising
- creating, by a computer, an edge mask of each of a plurality of axial image slices included in a volumetric image;
- identifying, by the computer, a symmetry axis of each edge mask;
- and
- fitting, by the computer, a plane to the symmetry axes, the plane defining a mid-sagittal plane estimate.
An image processing system comprising:
- a computer;
- and
- a module executable by the computer and configured to:
- create an edge mask of each of a plurality of axial image slices included in the volumetric image,
- identify a symmetry axis of each edge mask,
- fit a plane to the symmetry axes,
- determine a mid-sagittal plane estimate based on fitting a plane to the symmetry axis, and
- extract a mid-sagittal plane approximation based on the mid-sagittal plane estimate.
A non-transitory computer readable medium encoded with a plurality of processor-executable instructions for performing image processing, the instructions including instructions for:
- creating an edge mask of each of a plurality of axial image slices included in a volumetric image;
- identifying a symmetry axis of each edge mask;
- fitting a plane to the symmetry axes, the plane defining a mid-sagittal plane estimate;
- and
- extracting a mid-sagittal plan image from the volumetric image based on the mid-sagittal plane estimate.
