  • 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.

  • Publication number: 20230233176
    Abstract: Example implementations can include a method of calibrating orientation of a cerebral sensor and generating feedback from an injector for a cerebral sensor, by scanning an anatomical structure, by a cerebral sensor, proximate to the scan position and satisfying a first threshold, obtaining at least one cranial signal from the cerebral sensor in accordance with a first pathway over the anatomical structure, obtaining from the cranial signal a point corresponding to the anatomical structure, storing the obtained point to a point cache operable to store one or more points, in response to a determination that the point satisfies a second threshold, modifying the first pathway for actuating the cerebral sensor, in response to the determination that the obtained point satisfies the second threshold, selecting an optimized point from the point stack, and actuating the cerebral sensor continuously based on the optimized point.
