Abstract
A system and method for performing shape-constrained aortic valve landmark detection using 3D medical images is provided. A rigid global shape defining initial positions of a plurality of aortic valve landmarks is detected within a 3D image. Each of the plurality of aortic valve landmarks is detected based on the initial positions.
Claims33
A method for aortic valve landmark detection, comprising:
- detecting a global rigid shape defining initial positions of a plurality of aortic valve landmarks in a 3D medical image, wherein the global rigid shape is a shape that encompasses all of the plurality of aortic valve landmarks;
- individually detecting each of the plurality of aortic valve landmarks in the 3D medical image within search regions determined based on the initial positions of the plurality of aortic valve landmarks defined by the global rigid shape.
An apparatus for aortic valve landmark detection, comprising:
- means for detecting a global rigid shape defining initial positions of a plurality of aortic valve landmarks in a 3D medical image, wherein the global rigid shape is a shape that encompasses all of the plurality of aortic valve landmarks;
- means for individually detecting each of the plurality of aortic valve landmarks in the 3D medical image within search regions determined based on the initial positions of the plurality of aortic valve landmarks defined by the global rigid shape.
A non-transitory computer readable medium encoded with computer executable instructions for aortic valve landmark detection, the computer executable instructions defining steps comprising:
- detecting a global rigid shape defining initial positions of a plurality of aortic valve landmarks in a 3D medical image, wherein the global rigid shape is a shape that encompasses all of the plurality of aortic valve landmarks;
- individually detecting each of the plurality of aortic valve landmarks in the 3D medical image within search regions determined based on the initial positions of the plurality of aortic valve landmarks defined by the global rigid shape.
