Embodiment 1
[0032] A method for screening new coronary pneumonia based on deep learning, specifically comprising the following steps:
[0033] S1. Extract the mask of the effective area of the lungs
[0034] S2. Use the extracted mask to segment the effective area of the lungs, reduce the influence of irrelevant areas, and normalize the Hu value of the original CT to 0-255;
[0035] S3. Use the 3D convolutional neural network to segment out the lung lesion area, and output the location information of the lesion area, including the coordinates (x, y, z) of the center point and the diameter d of the lesion area;
[0036] S4. To detect the two-dimensional image of the lesion area in the middle layer of the lesion area, and obtain the images adjacent to the upper and lower sides at the same time, a total of three images
[0037] S5. Send the above-mentioned classified images into a two-dimensional classification network for training to determine whether it is COVID-19, influenza A or n...
Embodiment 2
[0043] This embodiment is a web interface-based screening system for new coronary pneumonia designed on the basis of Embodiment 1, including:
[0044] Image acquisition module, used to collect CT original compressed files;
[0045] The decompression module is used to decompress the CT original compressed file collected by the image acquisition module;
[0046] A format judging module is used for judging the format of the decompressed file obtained by decompressing the decompression module, and screening and obtaining the CT image in the lung window format in the CT;
[0047] The data processing module is used to calculate and process the CT image in lung window format in the CT screened by the format judging module, and calculate the overall disease type and probability of a single patient;
[0048] The display module is used to display the processing result of the data processing module.
[0049] This embodiment develops a web application interface for uploading the origina...
