Problems solved by technology

The existing methods for segmenting vertebrae from spine images are often not accurate enough due to noise interference. Although some methods denoise the image before segmentation, the effect of denoising is not ideal.

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

Abstract

The invention relates to the technical field of nuclear magnetic image processing, and discloses a spine image processing method based on a nuclear magnetic image, which comprises the following steps: S1, constructing a generative adversarial network which comprises a feature extraction module for feeding back a feature loss value; s2, training a generative adversarial network to generate a virtual noise-free spine image according to the original spine image; s3, processing the original spine image by using a generative adversarial network to obtain a virtual noiseless spine image; s4, segmenting a vertebra region from the virtual noiseless vertebra image; according to the spine image processing method based on the nuclear magnetic image, a generative adversarial network is trained by utilizing an original spine image with noise and a real noiseless spine image to achieve the purpose of removing noise, then the generative adversarial network is utilized to process the original spine image to obtain a virtual noiseless spine image, vertebrae are segmented from the virtual noiseless spine image, and the spine image is obtained. Therefore, the interference of noise on the vertebra segmentation process is avoided.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic image processing, in particular to a spine image processing method based on nuclear magnetic imaging. Background technique [0002] Nuclear magnetic imaging is to apply a radio frequency pulse of a specific frequency to the human body in a static magnetic field, so that the hydrogen protons in the human body are excited to generate magnetic resonance. After the pulse is stopped, the protons will generate magnetic resonance signals during the relaxation process. Signal reception, spatial encoding and image reconstruction, etc., to obtain medical images. Since MRI images can clearly show substantial lesions such as tumors, inflammation, and trauma in the spinal cord, MRI images of the patient's spine are often taken in the diagnosis of related diseases. [0003] With the increasing number of patients with spinal diseases, doctors have a heavy task of examining the MRI images of the spine. ...
