Lung lobe segmentation method and device and storage medium

Abstract

The invention discloses a lung lobe segmentation method and device and a storage medium, and relates to the field of medical image processing, and the method comprises the steps: obtaining lung imagesat multiple moments in a breathing process; determining a to-be-segmented lung image in the multi-moment lung image, wherein the lung image except the to-be-segmented image is used as a first lung image; fusing the to-be-segmented lung image by using at least one first lung image to obtain a fused lung image, the at least two first lung images comprising at least one lung image at a moment beforethe to-be-segmented image and / or at least one lung image at a moment after the to-be-segmented image; and segmenting the fused lung image by using a preset lung lobe segmentation model to obtain a lung lobe image of the lung image to be segmented. The problem that the segmentation effect is poor due to the fact that feature information of lungs (leaves) is insufficient at present is solved.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a lung lobe segmentation method, device and storage medium. Background technique [0002] The blunt upper end of the lung is called the lung apex, which protrudes upwards through the upper thorax into the root of the neck. The base is located on the top of the diaphragm. The entrance and exit of lymphatic vessels and nerves are called hilum, and these structures that enter and exit the hilum are wrapped together by connective tissue and are called lung roots. 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 a horizontal fissure in addition to the oblique fissure. [0003] At present, no matter whether traditional machine learning or deep learning is used to segment lung lobes, the classification is based on the characteristics of the lung (lobe). Therefore, the characteristics of...
