Abstract

The present application discloses a brain injury region segmentation method and apparatus for magnetic resonance images acquired on different scanning devices. The method includes receiving a first nuclear magnetic resonance image to be processed on a first scanning device and a second nuclear magnetic resonance image to be processed on a second scanning device; Converting the first to-be-processed nuclear magnetic resonance image and the second to-be-processed nuclear magnetic resonance image to a common domain by a converter respectively; And performing brain injury segmentation on the converted MRI image in the common domain. The present application solves the technical problem of poor effect of lesion segmentation processing on magnetic resonance images from different scanning apparatuses. The present application can better segment brain lesions on MR images acquired on different scanning devices, thereby accurately detecting cerebral infarction regions.

Description

technical field [0001] The present application relates to the fields of image processing and medical treatment, and in particular, relates to a method and device for segmenting brain injury regions of nuclear magnetic resonance images collected on different scanning devices. Background technique [0002] Cerebral infarction, also known as ischemic stroke, refers to the localized ischemic necrosis or softening of brain tissue caused by cerebral blood supply disturbance, ischemia and hypoxia. Cerebral infarction is the most common type of cerebrovascular disease, accounting for about 75%, with an average fatality rate of 10% to 15%. The disability rate is extremely high, and it is very easy to relapse. The mortality rate of recurrent stroke increases significantly. Therefore, accurate detection of cerebral infarction regions from nuclear magnetic resonance (full name in English: Magnetic Resonance, MR for short) is of great significance for timely detection of risks.
