Method and system for automatically extracting magnetic resonance image corpus callosum

Abstract

The invention discloses a method and system for automatically extracting the extracting magnetic resonance image corpus callosum. The method comprises the steps of according to a midsagittal plane T1 weighted nuclear magnetism brain image, determining a brain outline threshold value and a corpus callosum threshold value; performing threshold segmentation on the image according to the brain outline threshold value and the corpus callosum threshold value to respectively obtain a brain outline binary image and a corpus callosum binary image; respectively performing margin tracing on the brain outline binary image and the corpus callosum binary image to acquire a brain outline position and a corpus callosum margin cluster; establishing a decision tree, and screening marginal information to determine a corpus callosum region; determining an angle of inclination and a central position of a brain scanning line set according to the corpus callosum region. By means of the method and system, the corpus callosum in the midsagittal plane T1 weighted nuclear magnetism brain image can be extracted automatically, automatic regulation of the scanning line set during brain scanning can be completed according to information on the corpus callosum and the like, scanning efficiency is increased, no manual regulation is needed, time and labor are saved, an strong practicability is achieved.

Description

technical field [0001] The present invention relates to the technical field of magnetic resonance imaging image processing, in particular to a method and system for automatically extracting a magnetic resonance image corpus callosum. Background technique [0002] Magnetic resonance imaging (MRI for short) refers to the use of corresponding radio frequency pulses to excite the hydrogen nuclei (protons) of the subject placed in a static magnetic field, and the resulting magnetic resonance signals are collected and processed by a computer to reconstruct images. Because magnetic resonance imaging technology has the advantages of no ionizing radiation damage, high soft tissue contrast, high image resolution, flexible selection of imaging parameters and scanning orientation, and the ability to display blood vessels without contrast agents, it is widely used in clinical medical diagnosis. Its application and development The prospects are very bright. [0003] Medical image segment...
