Embodiment Construction
[0060] Most of the patients admitted to the emergency department and fever clinic are patients with a short course of disease, and their lung images have less consolidation, so it is not suitable to use some existing schemes that use single-source CT image data to determine the type and severity of pneumonia. The embodiment of the present invention provides a method and device for rapid screening of pneumonia images of unknown cause. According to the characteristics of lung images of patients admitted to emergency departments and fever clinics, comprehensive imaging data and other pathological information, such as laboratory indicators, patient symptoms, etc. Fusion analysis modeling, using the image analysis model to quickly and accurately make a comprehensive judgment on the condition.
[0061] Firstly, the process of establishing the image analysis model will be described in detail below.
[0062] like figure 1 As shown, it is a flowchart of establishing an image analysis ...

The invention discloses an unknown pneumonia image rapid screening method and device. The method comprises the following steps: establishing an image analysis model by using a small amount of acquiredlung CT image sequences, CT data and related data in advance, wherein the related data comprises any one or more of medical records and assay indexes; acquiring patient lung CT image data and relateddata of the patient lung; performing fusion processing on the CT image data and the related data thereof to obtain multi-dimensional features; and inputting the multi-dimensional features into the image analysis model, and obtaining lung disease categories and confidence thereof according to the output of the image analysis model. According to the invention, early warning can be rapidly and accurately carried out on viral pneumonia patients with unknown causes, and the diagnosis and treatment efficiency of pneumonia diseases is improved.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a method and device for rapid image screening of pneumonia of unknown cause. Background technique [0002] COVID-19 caused by SARS-COV-2 is currently raging around the world, and the number of cases is increasing rapidly. In addition, the early symptoms of the disease are mild and there are mild cases, so it is difficult to be diagnosed and isolated in time. serious threat and caused huge losses to the social economy. A number of studies have shown that chest imaging has a high predictive value in the diagnosis of COVID-19 patients. At the same time, early identification of pneumonia of unknown cause in patients with lung infection and timely early warning are of great significance to the prevention and treatment of new major infectious diseases. [0003] Although the infectious disease prevention and control system has been continuously improved in recent years, and the level of...
