Abstract

The invention provides a positioning method and device for a focus in a lung lobe. According to the method, key points of the lung lobe in a reference image are annotated, the reference image with theannotated key points is input into a to-be-trained convolutional neural network, the convolutional neural network is trained, and the obtained neural network can automatically position the key pointsin a lung CT image in high quality. After the positions of the key points are obtained, through the method and the device, coordinates of the focus in a lung can be automatically mapped into coordinates in a lung three-dimensional model made in advance, and a specific lung segment of the lung lobe of the lung where the focus is located is determined.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a method and device for locating a lesion in a lung lobe. Background technique [0002] Currently, lung cancer is the most common cancer in the world, and its incidence rate is increasing year by year. The survival rate of lung cancer is highly related to the stage of the disease when it is first diagnosed. Imaging diagnosis of lung cancer is an important means to detect early lung cancer. At present, intelligent medical care is an important content to promote the development of my country's health service and health industry and better protect people's health. , Intelligent medical care will assist us to allocate medical resources more rationally. With the arrival of population aging, solve the problem of medical convenience. Therefore, applying big data-driven artificial intelligence to early lung cancer imaging diagnosis, through machine-assisted doctors, can improve ...
