Automatic brain infarction detection system on magnetic resonance imaging and operation method thereof

Abstract

The present disclosure provides an operating method of an automatic brain infarction detection system on magnetic resonance imaging (MRI), which includes steps as follows. Images corresponding to different slices of a brain of a subject are received from the MRI machine. The image mask process is performed on first and second images of the images. It is determined whether the cerebellum image intensity and the brain image intensity in the first image are matched. When the cerebellum image intensity and the brain image intensity are not matched, the cerebellar image intensity in the first image is adjusted. The first image is processed through a nonlinear regression to obtain a third image. A neural network identify an infarct region by using the first, second and third images that are cut. By means of the technical scheme, the position of the focus on magnetic resonance imaging is accurately detected, and diagnosis quantification of a physician on magnetic resonance imaging is more efficiently helped clinically.

Description

technical field [0001] The present invention relates to a system and its operating method, and in particular to a magnetic resonance imaging automatic cerebral infarction detection system and its operating method. Background technique [0002] After cerebral infarction, the energy metabolism of brain tissue is destroyed, and a large amount of extracellular water enters the cells, causing the increase of intracellular water molecules and the decrease of extracellular water molecules, resulting in restricted diffusion, but the water content in the ischemic area will not Changes are only caused by changes in the water content inside and outside the cells, resulting in restricted diffusion, so conventional MRI examinations such as T1, T2, FLAIR... etc. are often unable to detect. [0003] Therefore, how to provide an automatic cerebral infarction detection system and its operation method has become an important issue. Contents of the invention [0004] The present invention p...
