Abstract

The embodiment of this specification discloses a positioning method and system based on DSA images, which belong to the technical field of medical imaging and computer. The embodiment of the present specification solves the problem that the "naked eye observation method" is greatly affected by subjective consciousness and takes a long time by locating the target area in the 3D DSA image to be processed. The positioning method includes: from the three-dimensional DSA image to be processed, adopting the method of maximum density projection to obtain two-dimensional images of the target direction respectively; Finding results: fusing the search results of the target area in the target direction to obtain the positioning area of ​​the target area in the three-dimensional DSA 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 three-dimensional DSA image, reducing the time for human observation, thinking, and 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. The "eye observation method"...
