Benefits of technology

This patented technique uses an X-ray imaging system with computed tomography (CT) scans for acquiring images from different parts of the body's surface during medical procedures or treatments such as brain surgery. By analyzing these acquired x- ray fluoroscopic images, it becomes possible to identify specific areas within the patient’ s skull that are associated with important structures like arteries called vasculature. These identified areas can be used by physicians to help make informed decisions about treatment options more accurately than previously done manually.

Problems solved by technology

The technical problem addressed by this patented method relates to improving accurate blood vessel centroids extractions from magnetic resonance images during strokes without sacrificing resolution capabilities or requiring extensive post-processing work.

Abstract

The invention discloses a head-neck blood vessel center line extraction method and device. The method comprises the steps of obtaining a blood vessel segmentation result and a blood vessel thermogramresult according to a head blood vessel CTA image; inputting a blood vessel skeleton line extracted based on the blood vessel segmentation result into a preset network model for blood vessel classification and naming, and obtaining blood vessel starting and ending point data; and extracting a head and neck blood vessel center line according to the blood vessel starting and ending point data and the blood vessel thermogram result. The technical problem of low blood vessel center line extraction accuracy in related technologies is solved. Through the method and the device, the purpose of extracting the blood vessel center line by combining the local detail information and the global structure information of the head and neck blood vessels is achieved, so that the technical effect of improving the accuracy of extracting the head blood vessel center line is achieved.
