The application discloses an aneurysm segmentation landing zone positioning and identifying method and system based on an optimal blood flow guiding model, and the method comprises the following steps: collecting image data of a target blood vessel region, and pre-processing the image data to obtain a blood vessel enhanced image; performing binaryzation on the blood vessel enhanced image to obtain a blood vessel cavity binary mask; extracting a tree-shaped blood vessel center line from the blood vessel enhanced image by using a blood vessel center line extraction algorithm; analyzing the tree-shaped blood vessel center line to obtain a multi-modal fusion feature vector; predicting a neck aneurysm probability value of the multi-modal fusion feature vector by using a pre-constructed neck aneurysm detection deep learning model, and screening a candidate neck aneurysm region and a parent artery region; and performing membrane membrane on the candidate neck aneurysm region and the parent artery region by using a blood vessel cavity three-dimensional binary mask, and extracting a device anchoring landing zone. According to the scheme, the neck aneurysm precisely positioned by the membrane membrane is taken as a starting point, and an anchoring landing zone section can be accurately screened out by searching upstream and downstream along the parent artery center line.

The present invention provides an aneurysm neck embolization member with flexibility in the neck region, and a method for manufacturing the aneurysm neck embolization member. [Solution] The device has a main body (collectively referred to as a body 52, neck 53, head 54, etc.) made of a tubular mesh material knitted by weft knitting to be flexible, and the main body includes a neck 53 that can fit into the neck of the aneurysm from the inside, and a body 52 knitted continuously with the neck 53 and inserted into the inside of the aneurysm, with the neck 53 interposed between one end in the axial direction and the other end of the neck 53, and the other end of the neck facing the neck N of the aneurysm from the side of the parent artery located outside the aneurysm and locked to the neck N of the aneurysm.

This application discloses a device and storage medium for auxiliary diagnosis and treatment decision-making for aneurysms. The device includes a processor and a memory, enabling the following operations: segmenting the aneurysm region and the parent artery region based on original three-dimensional vascular images; calculating key morphological parameters of the aneurysm based on the aneurysm region and the parent artery region; determining the aneurysm neck type based on the key morphological parameters, obtaining a neck classification result; dividing the aneurysm region into a main region and sub-regions; calculating three-dimensional spatial geometric parameters between the main region and the sub-regions; and determining the decision result for auxiliary diagnosis and treatment of the aneurysm based on the neck classification result and the three-dimensional spatial geometric parameters. Using the solution of this application, the aneurysm and parent artery can be automatically segmented, key morphological parameters can be accurately calculated, the neck type can be intelligently classified, complex substructures can be analyzed, and treatment suggestions can be output, providing objective and quantitative decision support for clinicians.
