Abstract

The invention relates to a lung lobe and tracheal tree-based registration method and device and a storage medium., and relates to the field of image processing. The method comprises the steps: obtaining a plurality of groups of lung lobe images and a plurality of groups of tracheal tree images in a breathing process, and enabling the plurality of groups of lung lobe images and the plurality of groups of tracheal tree images to be respectively lung lobe images and tracheal tree images obtained at a plurality of moments; determining common levels of tracheal trees in the plurality of groups of tracheal tree images respectively; taking an edge point/or a branch point of the tracheal tree corresponding to the common level as a first key registration point; determining lung lobe form edge points of the multiple groups of lung lobe images as second key registration points; and based on the first key registration point and the second key registration point, completing registration of any twogroups in the multiple groups of lung lobe images. The problem that lung lobe registration cannot be carried out or lung lobe registration is inaccurate at present is solved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a lung lobe and tracheal tree-based method and device, electronic equipment, and a storage medium. Background technique [0002] When doing medical image analysis, it is often necessary to analyze several images of the same patient together, so as to obtain comprehensive information of the patient and improve the level of medical diagnosis and treatment. To do quantitative analysis on several different images, we must first solve the problem of strict alignment of these images, which is what we call image registration. Medical image registration refers to seeking a kind of (or a series of) spatial transformations for a medical image to make it consistent with the corresponding points on another medical image. This consistency means that the same anatomical point on the human body has the same spatial position in the two matching images. The result of regis...
