Abstract

The invention relates to an image feature point determination method and device, computer equipment, a storage medium and a computer program product. Obtaining perfusion image data, and obtaining a first feature map and an attention map corresponding to the perfusion image data according to the perfusion image data; inputting the first feature map and the attention map into a candidate point generation model to obtain candidate feature points corresponding to the perfusion image data; determining a target feature point of the perfusion image data based on the candidate feature point; according to the embodiment of the invention, the method can automatically select the arteriovenous points, obtains the arteriovenous points which meet the requirements and are high in accuracy, does not need manual participation in the selection process of the arteriovenous points, shortens the selection time of the arteriovenous points, reduces the labor cost, and improves the efficiency. And the problem of inaccurate selection of the arteriovenous points caused by the influence of subjective factors of the user can be avoided, the selection efficiency of the arteriovenous points is improved, and the selection accuracy of the arteriovenous points can also be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method, device, computer equipment, storage medium and computer program product for determining image feature points. Background technique [0002] Perfusion imaging continuously scans the region of interest through the rapid injection of contrast agent in the vein. According to the scanning results of the region of interest, the change of blood perfusion in the region of interest can be quantified, which is of great significance for clarifying the blood supply of the lesion. Usually, the blood perfusion changes in the region of interest are mainly obtained based on the characteristics of the arteriovenous points in the scan results of the region of interest, but the characteristics of different arteriovenous points in the region of interest are different, and different arteriovenous characteristics Corresponding to the variation of blood perfusion in the reg...
