Problems solved by technology

That is to say, most of the determination of diseases in the prior art depends on the diagnosis of doctors. However, because the medical level in various regions is very inconsistent, and the level of personal experience of doctors is also uneven, the traditional method of diagnosing diseases by doctors is vulnerable. The influence of regional medical level and doctor's personal experience level leads to the problem of large diagnostic errors

Abstract

The invention discloses a method and a device for analyzing pulmonary nodules. The method comprises the following steps: carrying out extraction from CT (Computed Tomography) images of the lung of a patient to obtain pulmonary nodule images, and carrying out feature extraction on the pulmonary nodule images of the patient by adopting a preset feature extraction neural network model to obtain corresponding feature vectors of the patient; and further, inputting the corresponding feature vectors of the patient into a preset classification neural network model so as to obtain analysis results, output by the preset classification neural network model, of the pulmonary nodules suffered by the patient. Because the models are obtained by training a large quantity of data, the results obtained through the models are more reasonable, so that the results have a certain scientific evidence. Compared with diagnostic ways of conventional doctors, diagnosis error ratios caused by doctor level difference can be reduced, so that the analysis accuracy of the pulmonary nodules can be improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a method and device for analyzing pulmonary nodules. Background technique [0002] With the increasingly serious environmental pollution, more and more diseases show a trend of high outbreak rate. The development of modern medical technology is very mature, and doctors can diagnose various diseases with medical knowledge and medical experience. That is to say, most of the determination of diseases in the prior art depends on the diagnosis of doctors. However, because the medical level in various regions is very inconsistent, and the level of personal experience of doctors is also uneven, the traditional method of diagnosing diseases by doctors is vulnerable. The influence of regional medical level and doctor's personal experience level leads to the problem of large diagnostic errors. [0003] Taking pulmonary nodules as an example, doctors usually need to artificially...
