Processing method of brain magnetic resonance diffusion weighted image and related product

Abstract

The invention discloses a processing method of a brain magnetic resonance diffusion weighted image and a related product. The method comprises the following steps: acquiring a magnetic resonance diffusion weighted image set of a target brain; and taking the image set as the input of a segmentation model, and processing the image set through the segmentation model to obtain an infarction core segmentation result image of the target brain. The segmentation model comprises a compression path and an expansion path, the image set is input from the initial end of the compression path, and the infarction core segmentation result image is output from the tail end of the expansion path. The SE module of the extension path is used for re-allocating weights for each channel of the feature splicing result and obtaining a new feature splicing result, so that the problem of feature redundancy caused by directly splicing different levels of image features by using the same channel weights is avoided, and the high accuracy of an infarction core segmentation result image is ensured. The SE module can effectively avoid gradient disappearance, so that the segmentation model can converge more quickly, and the image processing speed is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a processing method of cranial magnetic resonance diffusion-weighted images and related products. Background technique [0002] Acute ischemic stroke (AIS) is a disease with high morbidity, disability, mortality, recurrence and complications. The core infarction area refers to the area where the cerebral blood flow decreases by more than 30% compared with the normal brain tissue, and the brain tissue in this area is irreversibly damaged. The Alberta Stroke Program Early CT Score (ASPECT score) is an important imaging index for evaluating the blood supply area of ​​the middle cerebral artery (middle cerebral artery, MCA). Physicians can refer to the patient's ASPECT score to select a suitable treatment plan. [0003] At present, the images obtained by CT or magnetic resonance-diffusion weighted imaging (MR-DWI) can be used to obtain the brain images, and then ...

Problems solved by technology

However, when the classic U-Net network processes images, there are problems of slow processing speed and low accuracy of processing results.
