SYSTEM FOR PROCESSING MAGNETIC RESONANCE IMAGES USING AUTOMATIC SEGMENTING

摘要

An apparatus and method for performing automatic 3D image segmentation and reconstruction of organ structures, which is particularly well-suited for use on cortical surfaces is presented. A brain extraction process removes non-brain image elements, then classifies brain tissue as to type in preparation for a cerebrum segmentation process that determines which portions of the image information belong to specific physiological structures. Ventricle filling is performed on the image data based on information from a ventricle extraction process. A reconstruction process follows in which specific surfaces, such as white matter (WM) and grey matter (GM), are reconstructed.

主权项

1. An apparatus for automatically processing images of brain regions, comprising:
(a) a system configured for scanning a patient's brain in three dimensions to generate three dimensional (30) medical brain image data; (b) at least one processor configured for automatically performing image processing on said 30 medical brain image data; (c) a memory storing instructions executable by said processor; and (d) said instructions when executed performing steps comprising:
(i) (ii) segmenting cerebrum imaging which determines which portions of the image information belong to specific physiological structures;(iii) anatomical refinement comprising ventricle filling in response to ventricle information extracted from the image, removal of dura mater, and correcting subcortical area;(iv) reconstructing surfaces of the brain including both white and grey matter in response to generating a surface mesh and correcting mesh topology; and(v) wherein each of the above steps are performed in response to said programming without user interaction or intervention.
