Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] figure 1 It is a structural schematic diagram of the bronchial segmentation system of the present invention, the system 100 includes a first segmentation module 10, a bronchial enhancement module 20 and a second segmentation module 30, wherein:

[0043]The first segmentation module 10 is configured to segment and extract the total area of ​​lung and bronchi from the original lung image by using a three-dimensional region growing algorithm, and the total area of ​​lung and bronchi includes lung tissue and bronchi. Since the gray value of the lung tissue and the air in the bronchi is signific...

Abstract

The invention is applied to the field of medical image segmentation technology, and provides a bronchial partition method and a system thereof. The bronchial partition method includes the following steps: a first segmenting step, segmenting and extracting a main area of the lung and the bronchus from an original lung image through three-dimensional growth algorithm; a bronchus enhancing step, carrying out multiple times of expansion operations and multiple times of corrosion operations to the main area of the lung and the bronchus; and a second segmenting step, extracting the bronchus from the main area of the lung and the bronchus after the multiple times of expansion operations and multiple times of corrosion operations. The bronchial partition method strengthens the bronchus through information of vascular so as to avoid effect of gray value change, and a segmenting result of the bronchus is enabled to be more stable and accurate.

Description

technical field [0001] The invention relates to the technical field of medical image segmentation, in particular to a bronchial segmentation method and system. Background technique [0002] The lung is an important respiratory organ of the human body, including the left lung and the right lung, which are located on both sides of the chest, and each lung is connected by the bronchi and the trachea. The right lung is divided into three lobes by two fissures, and the left lung is divided into two lobes by one fissure. The bronchial tree starts from the trachea, and is a tree-like structure formed by the main bronchi, lobar bronchi, segmental bronchi, and the above branches. According to the segmental bronchi, the left and right lungs can be divided into ten segments. CT (Computed Tomography, computerized tomography), MRI (Magnetic Resonance Imaging, magnetic resonance imaging) and other imaging techniques can display the bronchi above the segmental bronchi with a diameter of ...
