Problems solved by technology

The third is that the information utilization rate of medical images is low, and medical images generally have high resolution, but doctors do not fully use some image information that actually exists but cannot be distinguished by human eyes during observation, resulting in a waste of a lot of useful information
Manual screening of pulmonary nodules and labeling of pulmonary nodule features often requires viewing hundreds of CT scan images, which not only consumes manpower, but also delays time, causing great inconvenience to doctors.
[0004] In summary, the problem of the existing technology lies in the low efficiency of related manual work such as diagnosing pulmonary nodules and labeling the characteristics of pulmonary nodules

Abstract

The invention provides a quick marking method and system based on pre-screening, and the method comprises the steps: obtaining a pre-screening detection result through the pre-screening of a pulmonarynodule in a CT scanning layer image; carrying out the classification of the CT scanning layer image according to the pre-screening detection result, obtaining a classification image, and displaying the classification image; obtaining first three-dimensional mark information, pre-screening modification information and second three-dimensional mark information according to the classification image.According to the invention, the method improves the screening accuracy of the pulmonary nodule through the combination of pre-screening and multi-surface three-dimensional marking, enables the locating of the spatial position of the pulmonary nodule to be easier, greatly reduces the workload of a worker, and improves the marking reliability.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a rapid labeling method and system based on pre-screening. 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 correlated with the stage of the disease when it is first diagnosed. Therefore, imaging diagnosis of lung cancer is an important means to detect early lung cancer. Missed and misdiagnosed. [0003] With the worsening of environmental factors such as smog, the incidence of lung cancer in China is rising. If the lesion cannot be effectively detected, the best time for treatment will be delayed and irreversible damage will be caused to patients. According to the first national "Chinese Medical Misdiagnosis Literature Database", the number of misdiagnosed people in Chinese clinical medicine is about 57 million per year, with a total misdia...
