SYSTEM FOR MEASURING CORTICAL THICKNESS FROM MR SCAN INFORMATION

摘要

A measurement apparatus (800) to measure cortical thickness, the measurement apparatus may include at least one controller (810) which may be configured to: obtain magnetic resonance (MR) scan information of a region-of-interest of at least a portion of a cerebral cortex of a subject; form first, second and third meshes each comprising a plurality of points situated apart from each other, the first and third meshes being situated at inner and outer cortical boundary layers, respectively, of the cerebral cortex and the second mesh being situated between the first and third meshes; and/or for each of a plurality of points of the second mesh: determine a closest point of the first mesh and a closest point of the third mesh, determine a distance between the corresponding closest point of the first mesh and the corresponding closest point of the third mesh, said distance being corresponding with a cortical thickness.

1. A measurement apparatus, comprising:
at least one controller which is configured to:
obtain magnetic resonance (MR) scan information of a region-of-interest of at least a portion of a cerebral cortex of a subject;form first, second, and third meshes each comprising a plurality of points situated apart from each other, the first and third meshes being situated at inner and outer cortical boundary layers, respectively, of the cerebral cortex and the second mesh being between corresponding points of the first and third meshes; andfor each of a plurality of points of the second mesh:
determine a closest point of the first mesh and a closest point of the third mesh,determine a distance between the corresponding closest point of the first mesh and the corresponding closest point of the third mesh, andassociate the determined distance with the corresponding point of the plurality of points of the second mesh.
