Zusammenfassung: | The invention discloses a stent internal leakage detection method, system and equipment based on an AI technology. The stent internal leakage detection method comprises the following steps: acquiring an image of a patient after an intravascular stent implantation operation; inputting the image into a first segmentation network to obtain a segmented image, and indexing the segmented image to obtain a coordinate point set of a support in the segmented image; obtaining a blood radiography image of the patient after the vascular stent implantation; inputting the blood radiography image into a second segmentation network to obtain a segmented image, and indexing the segmented image to obtain a blood radiography coordinate point set in the segmented image; calculating the minimum distance between the coordinate point set of the stent and the coordinate point set of the blood radiography; and comparing the minimum distance with a preset threshold value, and outputting a result indicating whether the risk of internal |
