Abstract

The embodiment of this specification discloses a positioning method and system based on DSA images. By positioning the target area in the two-dimensional DSA sequence image to be processed, it solves the problem that the "naked eye observation method" is relatively affected by subjective consciousness and costs a lot. A matter of time. The positioning method includes: using the first model to obtain a frame containing the target area from the two-dimensional DSA sequence image to be processed; extracting the suspected positioning area of ​​the target area; using the third model to obtain the image of the suspected target area; using the first model The fourth model obtains the positioning information of the target area; restores the positioning information of the target area to the frame where the target area is located, and obtains the positioning area of ​​the target area in the two-dimensional DSA sequence image to be processed. The DSA image-based positioning method and system provided in the embodiments of this specification can directly display the target area in the two-dimensional DSA sequence image, reduce the time for human observation, thinking and judgment, and improve the accuracy of judgment.

Description

technical field [0001] This description relates to the fields of medical imaging and computer technology, in particular to a positioning method and system based on DSA images. Background technique [0002] Intracranial aneurysm is a common vascular disease, which is a tumor-like protrusion of the arterial wall caused by local abnormal expansion of the intracranial artery lumen. According to reports, the prevalence of unruptured intracranial aneurysms in Chinese adults is as high as 7%. Rupture of unruptured intracranial aneurysms can lead to severe disability or even death. Therefore, early detection of intracranial aneurysms is of great significance. [0003] DSA (Digital subtraction angiography, digital subtraction angiography) is widely used in clinical practice as the gold standard for the diagnosis of intracranial arterial malformations and aneurysms. At present, the location of intracranial aneurysms mainly depends on visual observation. This "eye observation method...
