Pneumoembolism recognition device based on parameter sharing, terminal equipment and storage medium

Abstract

The embodiment of the invention discloses a pulmonary embolism recognition device based on parameter sharing, terminal equipment and a storage medium. The device inputs an image to be detected into a pre-trained first feature extractor to obtain a first feature; inputting the first feature into a pre-trained first classification network to obtain the probability that the to-be-detected image contains pulmonary embolism; inputting the to-be-detected image with the probability reaching a first threshold value into a pre-trained region detection network to detect the position of pulmonary embolism and intercepting a corresponding region image; inputting the regional image into a pre-trained second feature extractor to obtain a second feature; fusing the first feature and the second feature to obtain a mixed feature; and respectively inputting the mixed features into a pre-trained second classification network and a pre-trained third classification network so as to confirm the property type and the position type of the pulmonary embolism. And through combination of generality and characteristics of feature identification results corresponding to different lesion information dimensions, the precision of identification detection results is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular, to a pulmonary embolism identification device, a terminal device, and a storage medium based on parameter sharing. Background technique [0002] Pulmonary embolism, a disease caused by a blocked artery in the lungs, can be a serious or even life-threatening condition when every breath is stressful and painful. In the United States, the annual incidence is 300,000-600,000, and the number of deaths due to pulmonary embolism is > 100,000. It is one of the most deadly cardiovascular diseases. The my country Pulmonary Embolism Collaborative Group counted the number of pulmonary embolism cases in 40 hospitals, an increase of nearly 10 times compared with the 1990s, and the trend is increasing year by year. Therefore, timely diagnosis and correct treatment can greatly reduce the mortality rate. [0003] The clinical symptoms and signs of pulmona...
