Abstract

The embodiment of the invention discloses a lung lobe segmentation method, device, computer equipment and storage medium. Wherein, the method includes: performing image segmentation on the collected original lung image based on a preset image segmentation algorithm to obtain a preliminary lung lobe segmentation image, the preliminary lung lobe segmentation image includes a preliminary lung lobe segmentation and an initial lung fissure; Or at least one first target lung fissure line input from the original lung image, wherein the first target lung fissure line is a complete lung fissure line or a locally adjusted lung fissure line; The split is adjusted to obtain the segmented image of the target lung lobe. The embodiment of the present invention solves the problem that the accuracy of the automatic lung lobe segmentation results is limited by the quality of lung CT image data and the accuracy of the lung lobe automatic segmentation algorithm, and cannot meet the clinical needs. The accuracy of segmentation results meets the needs of clinical diagnosis.

Description

technical field [0001] Embodiments of the present invention relate to medical image processing technology, and in particular to a lung lobe segmentation method, device, computer equipment and storage medium. Background technique [0002] The lung is the most important respiratory organ of the human body. It is located inside the chest cavity and above the diaphragm. The human lung includes five different anatomical structures, namely the lung lobes, and the lung fissure is the boundary between different lung lobes. The left lung is divided into upper and lower lobes by an oblique fissure, and the right lung is divided into upper, middle, and lower lobes by an oblique and a horizontal fissure. [0003] With the development of modern computer technology and medical imaging technology, in the diagnosis of lung diseases such as emphysema and lung cancer, higher requirements are put forward for the location of lesions, so as to provide more effective reference for lung diagnosis ...
