Medical image brightness homogenization correction method

Abstract

The invention provides a medical image brightness homogenization correction method. The medical image brightness homogenization correction method comprises the steps: constructing a brightness defectimage set of a target medical image; performing deep convolutional neural network training by taking the target medical image as a standard to obtain an image brightness distribution feature; constructing an image brightness adjustment model according to the image brightness distribution characteristics; and training a to-be-corrected medical image according to the image brightness adjustment model to obtain a medical image with uniform brightness. An image brightness adjustment model (namely, a generative adversarial neural network) is constructed through image brightness distribution characteristics obtained through deep convolutional neural network training, and medical image brightness homogenization correction is automatically performed by utilizing the image brightness adjustment model, and the medical image utilization rate is improved, and the time and resource cost caused by re-scanning is reduced.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a medical image brightness uniform correction method. Background technique [0002] In medical imaging systems, image quality depends on many factors, such as spatial resolution, tissue contrast, signal-to-noise ratio, contrast-to-noise ratio, and image defects. In order to present the best image quality, hardware and scanning parameters are optimized according to different organs. However, there are still irresistible factors, such as hardware limitations or physiological factors of the subject, which affect the scan and often cannot reach the optimal setting. [0003] One of the biggest defects affecting image quality is image brightness, and uneven image brightness can affect diagnostic quality. For example, in magnetic resonance imaging, non-uniform radio frequency fields can cause uneven image brightness. In order to ensure the quality of image scanning, operators...
