CT image clear processing method, system and equipment for pulmonary infectious diseases

Abstract

The present invention relates to the field of image processing technology, and proposes a method, system and device for clear processing of CT images of pulmonary infectious diseases, including: screening out edge pixels of all pulmonary blood vessels according to the authenticity evaluation coefficient to obtain edge pixels of pulmonary blood vessels; obtaining ground-glass shadow characteristic values ​​of each pulmonary blood vessel edge area according to the grayscale distribution of pixels in each pulmonary blood vessel edge area and the authenticity evaluation coefficient; obtaining pulmonary ground-glass lesion area; obtaining the window width adjustment amplitude of the patient's lung image according to the difference in grayscale values ​​of pixels between the pulmonary ground-glass lesion area and the surrounding pulmonary ground-glass lesion areas; adjusting the window width of the patient's lung image according to the window width adjustment amplitude to obtain the adjusted patient's lung image. The present invention can provide a more detailed and clearer position and morphology of the pulmonary lesion area through the adjusted patient's lung image.
