Embodiment 1

[0046] Such as figure 1 As shown, the present application provides a method for constructing a localization model of a lesion area in a chest image, including:

[0047] S101. Acquire chest X-ray images of a specified number of chest disease patients; the chest X-ray images may use a large number of existing chest X-ray images of chest disease patients.

[0048] Then in steps S102-104, image preprocessing is performed on the X-ray image to obtain preprocessed image data.

[0049] S102, performing chest X-ray image segmentation, including: using the Unet network to train a chest segmentation model, and performing chest segmentation on all chest X-ray images to obtain segmented chest X-ray images. Specifically, it includes: B11. Preliminarily locate the chest area through connected domain analysis. B12. Delete the non-image area at the edge of the chest area. Such as figure 2 As shown, the picture on the right shows that the segmented chest radiograph (chest X-ray image) can...

Embodiment 2

[0071] The present application also provides a method for locating a lesion area in a chest image based on the above-mentioned locating model of a lesion area in a chest image, comprising the following steps:

[0072] A', input patient's chest X-ray image;

[0073] B', preprocessing the chest X-ray image to obtain preprocessed image data;

[0074] C'. Input the preprocessed image data into the trained localization model of the lesion area in the chest image to locate the lesion area in the chest image.

[0075] To sum up, the present application can quickly and accurately provide a location result of a lesion area in a chest image for the user's reference, so as to reduce the doctor's diagnosis time and improve the efficiency and accuracy of diagnosis.

Abstract

The present invention provides a construction method and application of a localization model of a lesion area in a chest image, comprising: A, obtaining chest X-ray images of a specified number of chest disease patients; B, performing image preprocessing on the X-ray images, to obtain preprocessed image data; C. input the preprocessed image data into a convolutional neural network model for training, so as to obtain a trained model for locating lesion areas in chest images. Based on the above, the present application can accurately predict the regional position of the lesion in the image through the above model for user reference, so as to greatly reduce the diagnosis time of doctors and reduce the rate of missed diagnosis and misdiagnosis.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a construction method and application of a localization model of a lesion area in a chest image. Background technique [0002] Chest diseases are directly related to the health of patients. As an economical and convenient detection method, chest X-ray is the main means of screening chest diseases. Doctors can use this X-ray to diagnose chest diseases. The efficiency and accuracy of diagnosis It all depends on the doctor's experience level. However, due to the lack of a large number of professional medical imaging doctors, it is difficult to guarantee the efficiency and accuracy of diagnosis. [0003] Therefore, there is an urgent need for a localization model of the lesion area in the chest image to quickly and accurately provide a localization result of the lesion area in the chest image for user reference, so as to reduce the diagnosis time of the doctor and improve the efficien...
