Abstract

The invention relates to a pulmonary artery blood vessel tree obtaining method and device, a storage medium and electronic equipment, and the method comprises the steps: carrying out the segmentationof a CTPA image so as to obtain a pulmonary parenchyma binary image which is used for indicating the position of pulmonary parenchyma in the CTPA image; determining an intrapulmonary blood vessel binary image according to the pulmonary parenchyma binary image, wherein the intrapulmonary blood vessel binary image is used for indicating the position of an intrapulmonary blood vessel in the CTPA image; segmenting an aorta blood vessel three-dimensional image to obtain an aorta blood vessel binary image, wherein the aorta blood vessel binary image is used for indicating the position of an aorta blood vessel in the aorta blood vessel three-dimensional image, and the aorta blood vessel three-dimensional image is the image corresponding to the aorta blood vessel in the CTPA image; splicing the intrapulmonary blood vessel binary image and the aorta blood vessel binary image into a combined binary image, and extracting the pulmonary artery blood vessel tree in the CTPA image by using a communication component with the largest voxel quantity in the combined binary image.

Description

Technical field[0001]The present disclosure relates to the technical field of image processing, and in particular to a method, device, storage medium and electronic equipment for obtaining a pulmonary artery vascular tree.Background technique[0002]With the continuous development of image processing technology, CT (English: Computed Tomography, Chinese: Electronic Computed Tomography) equipment has the characteristics of fast scanning time and clear images, which can effectively assist doctors in observing the condition of the scanned part. It has been used in the medical field. widely used. Especially for the judgment of the symptoms of pulmonary embolism (English: Pulmonary Embolism, abbreviation: PE), CTPA (English: Computed Tomography Pulmonary Angiogram, Chinese: CT Pulmonary Angiogram) technology can be used to construct a pulmonary artery tree to track the pulmonary artery blood vessels to detect Location of pulmonary embolism. Therefore, to accurately detect the location of p...
