12. A method for determining presence or absence of a neurological condition in a subject, comprising:
determining a curvature metric based on ultrasound data collected from a head of the subject;
determining uncertainty in identifying the presence or the absence of the neurological condition in the subject based on the curvature metric;
in response to determining the uncertainty, determining a velocity asymmetry metric based on the ultrasound data to address the uncertainty; and
in response to determining the velocity asymmetry metric, determining the presence or the absence of the neurological condition in the subject based on the velocity asymmetry metric.
