Abstract

The invention provides a three-dimensional pulmonary lobe segmentation method based on a CT image, and belongs to the field of computer aided medicine. According to the method, marker-based watershedtransformation is mainly carried out in a CT image, and the lung parenchyma is subdivided into five lung lobes. The method comprises the following steps: firstly, segmenting pulmonary parenchyma, trachea and blood vessels by adopting an automatic segmentation algorithm, and generating cost images for watershed segmentation and mark points belonging to different lung lobes by utilizing the information of pulmonary parenchyma, trachea and blood vessels; And then carrying out watershed transformation on the basis of the obtained cost image and the mark point to obtain an initial lung fissure area; And finally, combining the initial pulmonary fissure area information with information of pulmonary parenchyma, trachea and blood vessels to generate a new cost image, and performing watershed transformation again to obtain a final pulmonary lobe segmentation result.

Description

technical field

[0001] The invention relates to the field of computer-aided medicine, and relates to a three-dimensional lung lobe segmentation method based on CT images. Background technique

[0002] In recent years, with the rapid development of modern society, increasing industrial activities, air pollution has become more and more serious, and the incidence of lung diseases is also increasing year by year. Respiratory diseases, mainly chronic obstructive pulmonary disease, rank among the highest in the mortality rate of urban residents in my country, while lung cancer has become the malignant tumor disease with the highest mortality rate in my country. Therefore, analyzing the composition and structure of the lungs and exploring the causes and development of lung diseases have important clinical significance for the diagnosis and treatment of lung diseases.

[0003] The identification of lung lobes has very important applications in the evaluation of lung diseases and t...
