  • Patent number: 12343195
    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.

  • Publication number: 20050033174
    Abstract: A pulse Doppler ultrasound system and associated methods are described for monitoring blood flow and hemodynamics. The Doppler ultrasound system includes an ultrasound probe to emit ultrasound signals and detect reflected signals therefrom and further includes a processor coupled to the ultrasound probe and operable to process the detected reflected signals and calculate therefrom blood flow data for a plurality of locations at time intervals, the processor further operable to identify locations at which blood flow having a hemodynamic characteristic is present based on the blood flow data calculated for a plurality of the time intervals. A user interface coupled to the processor provides blood flow information based on the blood flow data, the blood flow information representative of detected blood flow and the presence of the hemodynamic characteristic.
