The invention provides a lung respiratory movement acquisition method based on a boundary meta-model and local region correction. The method mainly includes the following steps that 1, chest CT images of a patient are acquired in advance; 2, lung regions are subjected to image segmentation on sequential images; 3, the chest sequential images at different respiration moments are registered; 4, boundary conditions of lung tissue respiratory movement are acquired; 5, all parameters in a lung surface boundary meta-model are calculated in combination with the boundary meta-theory and stored; 6, about 30 groups of feature points are selected from the sequential images at different respiration moments; 7, the lung tissue respiratory movement is subjected to movement estimation through a linear interpolation method; 8, lung interior region movement information is updated according to movement information of the feature points. Compared with the prior art, non-uniformity and anisotropism of the respiratory movement can be shown, and the advantages of being high in calculation speed, convenient to implement, flexible in application and the like are achieved.
Description
technical field [0001] The invention relates to the field of acquiring lung breathing motion information, in particular to a method for acquiring lung breathing motion information based on a boundary element model and local area correction. Background technique [0002] Precision treatment is an important development direction of today's medicine. It is the product of the rapid development of computing technology, imaging technology and medical science. It can provide patients with effective treatment with minimal additional damage, minimize risks and improve patient prognosis. The diagnosis rate of lung cancer has also improved to a certain extent. At present, most puncture operations are performed under the guidance of traditional three-dimensional CT images, and it is also an emerging and effective method for the diagnosis and identification of lung cancer. Combined with pathology, histopathological diagnosis is made, which has the characteristics of high diagnosis rate ...
