  • Publication number: 20230329668
    Abstract: A method and system for monitoring ultrasound tests and generating images to visually summarize the test results, are described. The method includes receiving ultrasound test data representing blood flow in a blood vessel of several interconnected blood vessels of a brain, and determining, based on the ultrasound test data, a direction and one or more hemodynamic values at a location in the blood vessel. An image of the interconnected blood vessels of the brain is generated. The image includes a direction indicator corresponding to the direction and a hemodynamic indicator corresponding to the one or more hemodynamic values. A user may view the image to assess whether the blood flow in the blood vessel is normal. Other embodiments are also described and claimed.
