METHOD AND APPARATUS FOR DETERMINING MID-SAGITTAL PLANE IN MAGNETIC RESONANCE IMAGES

摘要

A computer-implemented method is disclosed for volumetrically determining the midsagittal plane (MSP) from a plurality of magnetic resonance (MR) images of the brain. A plurality of MR images are received and transformed into a 3D volumetric image defined in a 3D coordinate space. Semantic segmentation of the anterior commissure (AC) region, posterior commissure (PC) region, and third ventricular region within the 3D volumetric image is pre-processed to generate 3D mask images labeled as the AC region, PC region, and third ventricular region. It is performed based on the trained segmentation model. Based on the labeled 3D mask image, a 3D volumetric image of the segmented third ventricular region is created. The MSP is determined based on 3D volumetric images of the third ventricular region.
